Justin Bieber has apologized for not "bowing down" to Seth Rogen.

The comedy actor recently slammed the 20-year-old singer for not acting interested when he introduced himself after Justin had specifically requested a meeting.

Now the musician has apologized to Seth, explaining why he reacted the way he did.

"Seth Rogan sorry I didnt bow down when I asked 2 meet u was probably a bit shy and didn't want to be over the top but still. love ur movies. (sic)," he posted on Twitter.

The feud began when the 32-year-old and Justin both appeared on a German talk show. The "Baby" singer asked to meet up with Seth, but then appeared uninterested.

“I was like, 'Sure, I'll meet him,'" Seth explained on The Howard Stern Show. "So I went outside to meet him and he was acting like I asked to meet him! It was very nonchalant, 'Yo man. What's up?' and I was like, 'What the f--k, I don't give a f--k... I don't want to meet you. Don't act all nonplussed to meet me. I didn't want to meet you. I was totally cool not meeting you…' But I was like, fine, I wouldn't have said anything, I was like, 'He's a bit of a motherf---er.'

"He's a good example of someone you meet, who you think you're going to hate, and then you get to hate him as much as you thought. You meet him, and he lives up to every one of your expectations of how you hope he will be."

Seth also slammed Justin publicly on Twitter in January.

"All jokes aside, Justin Bieber is a piece of s--t," he wrote.

  • Sharon and Kelly Osbourne vs. Lady Gaga

    It's quite the saga with these three, really: It all started when Kelly Osbourne <a href="http://www.mirror.co.uk/3am/celebrity-news/kelly-osbourne-has-harsh-words-for-lady-404664">called Gaga a"Butterface,"</a> then jokingly asked if the <a href="http://www.thesun.co.uk/sol/homepage/showbiz/tv/4547126/Kelly-Osbourne-reckons-Lady-Gaga-is-pregnant.html">singer is pregnant when she gained weight</a>. Gaga's loyal fans took it to heart, apparently, and in an interview later on, Osbourne said they bullied her and called them <a href="http://www.huffingtonpost.com/2013/01/09/kelly-osbourne-lady-gaga-bullying-fat_n_2440673.html?utm_hp_ref=social-media">"the worst."</a> In response (and in her Little Monsters defense), Gaga wrote an open letter to the young Osbourne and said her work "is rooted in criticism, judgment." That's when Kelly's mother, Sharon Osbourne, <a href="http://www.huffingtonpost.com/2013/01/11/sharon-osbourne-lady-gaga-kelly-osbourne_n_2455327.html?utm_hp_ref=celebrity">jumped in and called Gaga a "publicly seeking hypocrite and an attention seeker."</a> Two days later, Gaga replied to Sharon and urged the Osbournes to cease fire and <a href="http://www.huffingtonpost.com/2013/01/13/lady-gaga-kelly-osbourne-feud-responds-sharon-osbourne_n_2467273.html">make the world a better place</a>.

  • Jennifer Lawrence vs. Kristen Stewart

    When Lawrence's "The Hunger Games" came out, it was naturally compared to "Twilight," both huge YA franchises. <a href="http://www.gossipcop.com/twilight-hunger-games-feud-fight-kristen-stewart-jennifer-lawrence-robert-pattinson-liam-hemsworth/">Rumors circulated at the time</a> that "Jennifer really wants to overthrow Kristen as Hollywood's young darling," and that Stewart called Lawrence "plain" in response. But after the two beauties chatted it up at the Oscars (Lawrence inquired about Stewart's crutches, <a href="http://www.huffingtonpost.com/2013/02/27/kristen-stewart-jennifer-lawrence-oscars_n_2774474.html">Stewart cheered on when Lawrence won best actress</a>), the rumors subsided. Until the sequel?

  • Hilary Duff vs. Lindsay Lohan

    Take two Disney starlets and one prepubescent popstar and you have a recipe for one of the most discussed celebrity feuds of the 2000s. Back in 2002, Aaron Carter reportedly broke up with or cheated on Hilary Duff, who he was dating for two years, to hook up with Lindsay Lohan. The 15-year-old Casanova then left Lohan to get back together with Duff. Though the girls should have been furious with Carter, they instead turned on each other. Their feud played out in the pages of magazines with both actresses <a href="http://today.msnbc.msn.com/id/8669450/ns/today-entertainment/t/lohan-says-duff-rebuffed-her-peace-attempt/" target="_hplink">taking shots at each other for years. </a> By 2007 the girls put their past behind them and made up. "We are both adults and whatever happened, happened when we were young," Duff <a href="http://www.people.com/people/article/0,,20033534,00.html" target="_hplink">told <em>People</em></a>. "It's over."

  • Jon Hamm vs. Kim Kardashian

    "Mad Men" star Jon Hamm recently made some unflattering <a href="http://www.huffingtonpost.com/2012/03/09/jon-hamm-slams-kim-kardashian-idiot-culture_n_1335411.html" target="_hplink">comments to <em>Elle UK</em> </a>about celebrity culture, putting reality TV queen Kim Kardashian in his crosshairs. "Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f**king idiot is a valuable commodity in this culture because you're rewarded significantly," he told the magazine. Kim responded on Twitter, <a href="http://www.huffingtonpost.com/2012/03/12/kim-kardashian-responds-jon-hamm-stupid_n_1339923.html?ref=the-kardashians" target="_hplink">writing</a>: "I just heard about the comment Jon Hamm made about me in an interview. I respect Jon and I am a firm believer that everyone is entitled to their own opinion and that not everyone takes the same path in life. We're all working hard and we all have to respect one another. Calling someone who runs their own businesses, is a part of a successful TV show, produces, writes, designs, and creates, 'stupid,' is in my opinion careless." When asked about his comments, <a href="http://www.eonline.com/news/jon_hamm_kim_kardashian_slam_not/301003#ixzz1p6Yz2tbE" target="_hplink">Hamm told E! News</a>, "It's surprising to me that this has become remotely a story. I don't know Ms. Kardashian. I know her public persona. What I said was meant to be more on pervasiveness of something in culture, not personal, but she took offense to it and that is her right."

  • Courtney Love vs. Dave Grohl

    It's a known fact that Courtney Love hates former Nirvana drummer Dave Grohl, and he is by no means fond of her. The two have been feuding over the rights to Nirvana's music since Kurt Cobain killed himself in 1994. Most recently, <a href="http://www.huffingtonpost.com/2011/11/15/courtney-love-explains-foo-fighters-rant_n_1095238.html" target="_hplink">Courtney explained</a> why she hates the Foo Fighters frontman, after playing a show in Brazil. "What I was saying, is Dave makes $5 million a show, he doesn't need the money. His mother's a banker, his father's a stock broker and he's making $5 million a show. Why the f**k then does he have a Nivana Inc. credit card and I don't? And last week he bought an Aston Martin on it," she said.

  • Miley vs. Selena Gomez & Demi Lovato

    Disney starlets do not play nice. In 2008, teen queen Miley Cyrus went head to head with Selena Gomez and Demi Lovato. BFFs Selena and Demi used to make goofy videos they would post to YouTube, much to the chagrin of Miley as it turned out. Miley and her BFF Mandy made a parody video where they mocked the other girls, making fun of their makeup and the gap in Demi's front teeth. The feud appeared to come out of nowhere. "To be honest I don't know what happened," <a href="http://newsroom.mtv.com/2008/08/01/the-miley-cyrus-selena-gomez-demi-lovato-feud-nonexistent/" target="_hplink">Selena told MTV</a>. "I though we were okay, but to be honest, I don't even know [Miley and Mandy]. And Demi has never met Miley. It's interesting -- that's all I'm going to say about it." They all eventually made up and became friends. <a href="http://www.aceshowbiz.com/news/view/00021443.html" target="_hplink">Miley addressed the feud in a YouTube video in 2009: </a> "So everyone's thinking there's a big feud between me and Selena and Demi. Actually, I'm going to have meatloaf with Demi tonight. I'm riding my bike to Demi's house. So I'm going to be partying with Demi 'cause we're friends, and I love her and she is always there for me. She is one of my bestest friends."

  • Donald Trump vs. Rosie O'Donnell

    There are many celebs who have feuded with Donald Trump, but his ongoing fight with Rosie O'Donnell remains the most memorable. In 2006, Rosie criticized Trump for not dethroning Miss USA Tara Conner after her drug scandal and she called him a "pimp" and "snake oil salesman." Never one to take things lying down, Trump responded by calling her a "big, fat pig" and a "loser." Their feud dragged on until no one wanted to hear what either of them had to say and it unfortunately started up again. <a href="http://www.accesshollywood.com/donald-trump-and-rosie-odonnell-feud-reignited_article_57986" target="_hplink">In December 2011, Trump tweeted</a>, "Same last name, same bad ratings - @lawrence and @rosie," and linked to a YouTube clip of himself ranting about how neither of their talk shows were doing well. Rosie tweeted back, "How many billionaires sell ties and have crappy non reality shows -- none - go back to selling snake oil #bankruptmuch?" Neither will spare the public of their immaturity and their feud continues today.

  • Will.i.am vs. Perez Hilton

    Gossip blogger Perez Hilton was confronted by the Black Eyed Peas at the Much Music Video Awards in 2009 and began hurling insults at Will.i.am and the rest of the band. Perez was <a href="http://www.huffingtonpost.com/2009/06/22/perez-hilton-called-willi_n_219088.html" target="_hplink">punched in the face</a> by Will.i.am's manager and the blogger later tweeted, "I was assaulted by Will.i.am of the Black Eyed Peas and his security guards. I am bleeding. Please, I need a police report. No joke." Will.i.am later denied Hilton's claims and Hilton shot back with a 12-minute video blasting the Black Eyed Pea as a "disgusting human being" and "a fucking liar." Perez later sued Will.i.am's manager and a s<a href="http://wonderwall.msn.com/music/perez-hilton-black-eyed-peas-manager-settle-suit-1537413.story" target="_hplink">ettlement was reached.</a>

  • Lindsay Lohan vs. Brandon Davis

    Who needs enemies when you have friends like Brandon Davis? Back in 2006, Lindsay Lohan was pals with Paris Hilton, until Paris accused her of trying to steal her boyfriend, Greek shipping heir Stavros Niarchos. Once Lindsay was on the outs with her socialite friends, oil heir Davis took it upon himself to brand Lohan with a nickname. While drunk in LA one night, Davis was filmed ranting about Lohan, <a href="http://www.tmz.com/2006/05/17/paris-and-brandon-davis-the-incredible-hatred-toward-lindsay/#.T2FG_HJSTdc" target="_hplink">dubbing her "fire crotch," and making other rude and disgusting claims. </a>

  • Kelly Osbourne vs. Christina Aguilera

    These ladies need to learn to keep their comments to themselves. Back in the day, Christina Aguilera apparently used to call Kelly Osbourne fat, and now that Kelly has slimmed down and Christina has gained a few pounds the tables have turned. Osbourne made sure to call attention to the singer's weight gain, not once, but twice in 2011. "Maybe she is just becoming the fat bitch she was born to be. I don't know. She was a c**t to me. And she bought my house," Osbourne said <a href="http://www.huffingtonpost.com/2011/08/04/kelly-osbourne-calls-christina-aguilera-a-fat-bitch_n_918063.html" target="_hplink">during an episode of "Fashion Police" that aired in August.</a> "She called me fat for so many f***ing years, so you know what? F**k you! You're fat too." Then in October, the <a href="http://www.huffingtonpost.com/2011/10/17/kelly-osbourne-i-was-never-as-fat-as-christina-aguilera_n_1015490.html" target="_hplink">singer was again the topic of discussion on the show: </a> "Lady Marmalade got into the peanut better again," quipped co-host Joan Rivers when criticizing Aguilera's too-tight outfit. "She called me fat for years, I was never that fat," Osbourne said and later added, "Trust me, I'm a 2/4. That is not a 2/4."

  • Shannen Doherty vs. Alyssa Milano

    Shannen Doherty has a reputation as Hollywood's bad girl and feuded with nearly all of her "Beverly Hills, 90210" castmates, and yet it was her feud with Alyssa Milano that will go down as the worst. The "Charmed" co-stars began fighting on set during the third season and it was reported that Shannen was jealous of Alyssa's popularity. Tension ran high on set and things grew so heated, producers had to bring in a mediator to resolve their issues. When they couldn't work things out, Shannen left the show.

  • Mariah Carey vs. Eminem

    Is there anyone Eminem hasn't feuded with? Eminem and Mariah Carey began to spar after he claimed that they used to have a sexual relationship. Mariah denied the relationship, telling Larry King, "I hung out with him, I spoke to him on the phone. I think I was probably with him a total of four times. And I don't consider that dating somebody." Mariah later mocked his claim in her video for "Obsessed," which featured an Eminem look-alike who was obsessed with her. The rapper retaliated with a number of songs that mentioned Carey and threatened to release nude photos of the singer as well as voicemails to prove they dated. In the song "The Warning" he raps: "Shut the fuck up before I put up all the phone calls you made to my house when you were "Wild N' Out" before Nick, when you was on my dick and give you something to smile about."

  • Charlie Sheen vs. Chuck Lorre

    When Charlie Sheen lost his mind in 2011, he dug his own grave and lost his job as the highest paid actor on television. Sheen went on a rampage, verbally attacking "Two and a Half Men" showrunner Chuck Lorre, after CBS suspended the series due to Sheen's insane behavior. After Lorre make a joke about Sheen, the <a href="http://www.people.com/people/article/0,,20469063,00.html" target="_hplink">actor attacked him, calling Lorre a "clown" </a>, and made a strange anti-Semitic dig, saying his real name is "Chaim Levine" (though his name is actually Charles Michael Levine). Sheen continued to blast Lorre as a "stupid, stupid little man and a p*ssy punk that I never want to be like." Now that Sheen appears to be sober, Lorre has <a href="http://articles.nydailynews.com/2012-01-11/news/30618049_1_half-men-fx-network-leaf" target="_hplink">chosen to take the high road.</a> "I wish him well. I'm glad he's happy and sober," he said in January 2012.

  • Lauren Conrad vs. Heidi and Spencer

    "You know what you did," Lauren Conrad screamed at Heidi Montag on an episode of "The Hills." Lauren and Heidi's friendship began to dissolve in 2007, when Heidi started dating Spencer Pratt. "He's a sucky person," she infamously told her one-time best friend. Heidi chose a relationship with Spencer over a friendship with Lauren and spread a rumor there was a<a href="http://www.justjared.com/2008/05/01/heidi-montag-lauren-conrad-feud/" target="_hplink"> Lauren Conrad sex tape floating around. </a> Heidi tried to repair things with Lauren, but she wasn't having it. "I want to forgive you and I want to forget you," Lauren told her as <a href="http://www.sheknows.com/living/march-madness-mix-up-gallery/cry-faces/lauren-conrad-3" target="_hplink">mascara ran down her face</a>. The feud eventually ended but they never repaired their friendship. As Spencer began to fade into obscurity he tried make himself relevant by burying the hatchet with Conrad, <a href="http://tv.yahoo.com/news/lauren-conrad-planning-ignore-spencer-pratts-apology-000504559.html" target="_hplink">wishing her a happy birthday</a> on Twitter in February 2012.

  • Chris Christie vs. Snooki

    New Jersey Governor Chris Christie has no love for the "Jersey Shore" cast and Snooki isn't fond of him either. Christie has been vocal about his distaste for the cast and has referred to them as "losers," and also vetoed a $420,000 tax credit for the MTV reality show in September 2011. Snooki doesn't appriaciate being called a loser and the pint-size reality star <a href="http://www.huffingtonpost.com/2012/02/01/snooki-refuses-to-vote-for-chris-christie_n_1247211.html" target="_hplink">tweeted that she wouldn't be voting for Christie for president </a> and added, "Love always, the "buffoons" from that degrading Jersey Shore show." Christie wasn't and isn't running for president, but Snooki regardless explained: "I DEF don't want a judgmental president who has NEVER met me in person. F that. idc who exploits me. But for a man wanting to be president&calling us names when he's never met us..no thanks. I'll stick w Obama."

  • Kid Rock vs. Steven Tyler

    Kid Rock had a big problem with Aerosmith frontman Steven Tyler taking on a new gig as a judge on "American Idol" in 2010. Kid Rock didn't believe a true rock star would even think about working for a show like "Idol" and proceeded to trash Tyler for it. <a href="http://today.msnbc.msn.com/id/39954827/ns/today-entertainment/t/kid-rock-slams-steven-tylers-american-idol-gig/#.T2ICPGLLwbI" target="_hplink">Rock told<em> Entertainment Weekly,</em></a> "I think it's the stupidest thing he's ever done in his life. He's a sacred American institution of rock and roll, and he just threw it all out the window. Just stomped on it and se it on fire." At a press conference, Tyler <a href="http://www.rollingstone.com/music/news/steven-tyler-on-kid-rock-hes-just-jealous-20101105" target="_hplink">responded</a>, "He's just jealous, he's just jealous. And he's working on his new record, so God bless him."

  • Chris Brown vs. Miranda Lambert

    Miranda Lambert was not happy to see Chris Brown performing at the Grammy Awards. "And Chris Brown Twice? I don't get it. He beat on a girl...Not cool that we act like that didn't happen," she tweeted referencing Brown's brutal 2009 assault on Rihanna. Brown responded indirectly by tweeting, "Hate all you want because I got a grammy now! That's the ultimate f*** off." Then at her concert, Lambert held up a handwritten poster that read, "Take notes Chris Brown" and said to the audience, "Listen, I just need to speak my mind. Where I come from, beating up on a women is never OK. So that's why my daddy taught me early on in life how to use a shotgun." Brown fired back in a series of tweets: "Using my name to get publicity? I love it! Perform your heart out! Go buy @miranda_lambert! So motivational and "PERFECT." Goodnight to all the people who live life and who aren't stuck in the past!"

  • Brett Ratner v. Olivia Munn

    In actress Olivia Munn's book "Suck It, Wonder Woman," she recounts her brief romantic dalliance with director Brett Ratner and didn't have anything nice to say about the size of his penis. Ratner <a href="http://www.ibtimes.com/articles/243711/20111104/brett-ratner-admits-banged-olivia-munn-promoting.htm" target="_hplink">addressed the claims on "Attack of the Show" saying</a>, "I used to date Olivia Munn, I'll be honest with everyone here, when she was Lisa...she wasn't Asian back then." He continued: "She was hanging out on my set of 'After the Sunset,' I banged her a few times. But I forgot her...because she changed her name...I didn't know it was the same person, so when she came and auditioned for me for a TV show I forgot her, she got pissed off, and she made up all these stories about me eating shrimp and masturbating in my trailer." Munn responded by tweeting a link to a <em>Cosmo</em> article she had written titled, "How to Stand up to an A-Hole," that detailed an incident with a director she called the "Douche."

  • LeAnn Rimes vs. Giuliana Rancic

    LeAnn Rimes is skinny -- so skinny that she has people worrying that she's not eating. The equally skinny Giuliana Rancic was one those people. Pot, meet kettle. The two skinny ladies battled it out <a href="http://www.huffingtonpost.com/2011/08/30/leann-rimes-responds-giuliana-rancic_n_941579.html" target="_hplink">telling each other to eat a sandwich. </a>

  • Ciara vs. Rihanna

    Rihanna and Ciara -- who both dated Chris Brown in the past -- got into a heated public spat in February 2011. First Ciara made a dig at Rihanna on "Fashion Police," saying: "I ran into her recently at a party. She wasn't the nicest. It's crazy because I've always loved and respected what she's done in fashion. It wasn't the most pleasant run-in." When Rihanna heard what Ciara had said, she fired back on Twitter. "My bad Ci, did I forget to tip you? How rude of me.... You gangsta huh? Ha." They volleyed insults and threats at each other and then Rihanna called a truce. "Ciara baby, I love you girl! You hurt my feelings real bad on TV! I'm heartbroken! That's why I retaliated this way! So sorry! Let's make up." Ciara accepted the apology and that was that.

  • Kourtney Kardashian vs. Farrah Abraham

    This might be one of the most ridiculous celebrity fights of all time. "Teen Mom" cast member Farrah Abraham didn't think things through when she criticized Kourtney Kardashian on Twitter. "I'm shocked Kourtney Kardashian is pregnant again Did she not learn anything from TEEN MOM? Maybe its a fake pregnancy like kims wedding SAD," she tweeted. Kourtney was understandably confused by the attack and tweeted back, "Why would I have anything to do with Teen Mom? I'm 32 years old! I may look young, honey, but don't get it twisted." While Kourtney suggested that Farrah had no idea what she was talking about, the "Teen Mom" star couldn't resist firing back at her: "Guess what! Age and money honestly do not change a person's poor choice. Quit making excuses," she tweeted. Kourtney's boyfriend Scott Disick also got in on the fight, sarcastically tweeting at Farrah, "We're not teenagers, ya f**king moron." When asked if he knew who she was, he responded, ""I just thought she was some shit stain on Twitter, no?" Sadly, this Twitter fight actually continued with Farrah later tweeting, "4 all who mistunderstood: regards to kourtney K.~I hope she takes her relationship w/her boyfriend more serious 4 their children-takecare." Shortly after, however, she couldn't resist getting one more word in with a jab at Disick: "Caught wind of these dramatic articles, w/ loser scott disick or some boyfriend of kourtneys, is Shit Stain < racist 4 black?" she wrote. "Great dad! NOT."

  • Anthony Bourdain vs. Paula Deen

    Celebrity chef Anthony Bourdain is not a fan of Paula Deen's cooking. In 2011 he told <em>TV Guide</em> she was "the worst, most dangerous person to America." Deen responded, claiming, "You know, not everybody can afford to pay $58 for prime rib or $650 for a bottle of wine. My friends and I cook for regular families who worry about feeding their kids and paying the bills . . . It wasn't that long ago that I was struggling to feed my family, too." Months later, after Deen announced she has Type 2 diabetes and was now a paid spokeswoman for a diabetes medication, Bourdain <a href="http://www.people.com/people/article/0,,20562258,00.html" target="_hplink">responded with a thinly veiled tweet</a>: "Thinking of getting into the leg-breaking business, so I can profitably sell crutches later." Deen fired back that Bourdain should "get a life".

  • Jonah Hill vs. Matthew Morrison

    Jonah Hill made it clear he was no fan of "Glee" star Matthew Morrison, when he appeared on "Late Night with Jimmy Fallon" in September 2011. Hill recalled a "douchey Hollywood party" where he tried to eavesdrop on a conversation between "Gossip Girl" actor Chace Crawford and Morrison, who had<a href="http://www.dlisted.com/2011/09/23/fight-fight-jonah-hill-vs-matthew-morrison" target="_hplink"> made a joke at Hill's expense at an event a few weeks earlier</a>. He then overheard the two drop his name and start laughing. Hill took the opportunity on "Late Night" to call out the "Glee" actor: "Matthew Morrison, you better bring your sh*t next time I see you...I'd like to see him sing his way out of this one," he said. Morrison responded by sending a goofy video to "Late Night," where he finished his joke about Hill and then accepted the actor's challenge, saying, "Nobody messes with someone from musical theater!" This extremely dorky feud <a href="http://www.mtv.com/news/articles/1673980/jonah-hill-matthew-morrison-sitter.jhtml" target="_hplink">eventually just blew over</a>.

  • Chelsea Handler vs. Michelle "Bombshell" McGee

    Chelsea Handler <a href="http://blog.zap2it.com/pop2it/2010/04/chelsea-handler-goes-after-michelle-bombshell-mcgee-some-more.html" target="_hplink">started a feud with Jesse James' tattooed mistress Michelle "Bombshell" McGee in 2010,</a> with a joke she wrote on her blog: "I guess she doesn't read magazines which makes sense, since she basically has one on her face." McGee responded on her Facebook page writing: "Chelsea, here's some free advice: Use some of that Botox from your forehead and put it in your flabby underarm skin. I've seen better wings in a bucket of KFC chicken." And later wrote, ""In all seriousness, Im a big fan of 'Chelsea Lately' ... I was laughing my ass off.... feel so honored to have a transexual [sic] poke fun of me ..." Don't mess with a comedian -- Handler didn't hold back with her response to McGee: "First of all, look at my forehead, you dumb bitch, okay? It moves ... You have a tattoo on your forehead, so you have had a needle in your forehead -- and probably Jesse James' balls. So shut your face."

  • Ryan Murphy vs. Kings of Leon

    This feud started after Kings of Leon declined to allow the Fox series "Glee," to cover one of its songs on a future episode. "Glee" creator Ryan Murphy was pissed and <a href="http://www.huffingtonpost.com/2011/01/26/kings-of-leon-vs-glee-nathan-followill-fires-back-at-ryan-murphy-in-homophobic-rant_n_814351.html" target="_hplink">sent a message to the band via <em>The Hollywood Reporter</em></a>: "F**K you, Kings of Leon," he said. "They're self-centered assholes, and they missed the big picture. They missed that a 7-year-old kid can see someone close to their age singing a Kings of Leon song, which will maybe make them want to join a glee club or pick up a musical instrument. It's like, OK, hate on arts education. You can make fun of Glee all you want, but at its heart, what we really do is turn kids on to music." KOL member Nathan Followill fired back with a homophobic dig at openly gay Murphy, tweeting: "Dear Ryan Murphy, let it go. See a therapist, get a manicure, buy a new bra. Zip your lip and focus on educating 7yr olds how to say f**k." Realizing how his comments could be seen, Followill later tweeted: "I'm sorry 4 anyone that misconstrued my comments as homophobic or misogynistic. I'm so not that kind of person. I really do apologize."

  • Tom Cruise vs. Brooke Shields

    In 2005, Tom Cruise seemed to have lost his marbles when he jumped on couches on Oprah's talkshow. He then lashed out at actress Brooke Shields, while on the "Today" show, telling Matt Lauer that Shields should not have taken antidepressants to combat the postpartum depression she was suffering from after the birth of her first child. Cruise, a Scientologist who shuns psychiatry, insisted the depression could be treated with "vitamins and exercise." Shields responded by writing an <a href="http://www.nytimes.com/2005/07/01/opinion/01shields.html" target="_hplink">op-ed piece in the <em>New York Times,</em> writing</a>: "I'm going to take a wild guess and say that Mr. Cruise has never suffered from postpartum depression ... And comments like those made by Tom Cruise are a disservice to mothers everywhere ...

  • Taylor Swift vs. Kanye West

    Kayne West infamously hijacked Taylor Swift's acceptance speech at the 2009 Video Music Awards, interrupting her to say, "I'm really happy for you. I'ma let you finish, but Beyoncé had one of the best videos of all time." Swift was dumbstruck by the incident and it seemed as if she didn't want to get into it with the rapper. "I don't know him, and I've never met him, so..." she said. "I don't want to start anything because I had a great night tonight." A year later she was literally singing a different tune. At the 2010 VMAs she p<a href="http://www.hollywoodlife.com/2010/09/13/taylor-swift-kanye-west-mtv-video-music-awards-youre-still-an-innocent-time-we-had-a-toast/" target="_hplink">erformed her new song</a> "You're Still an Innocent," a reference to the previous year's incident with West, basically calling him immature. "Thirty-two and still growing up now / who you are is not what you did / you're still an innocent," she sang. Kanye didn't have any right to fire back, but of course he did. At a concert in New York City, <a href="http://www.popeater.com/2010/11/24/kanye-west-concert-taylor-swift/" target="_hplink">West blasted Swift to his fans</a>: "Everybody needs a villain, don't we? We need to blame someone at all times ... I was emotional, that was not exactly the way I wanted to word it, but I wrote it, I rode it, just as Taylor never came to my defense in any interview, and rode the waves and rode it and rode it." The feud seems to have blown over, as Swift wore a blouse from Kanye West's spring 2012 collection in the <a href="http://www.hollywoodlife.com/2012/03/07/taylor-swift-kanye-west-design-harpers-bazaar-australia/" target="_hplink">pages of <em>Harper's Bazaar.</em> </a>

  • Bieber's Most Troublesome Moments

  • March 2011

    Justin had his first, very public, run in with the paps when he <a href="http://www.thehollywoodgossip.com/2011/03/justin-bieber-to-paparazzi-eff-you/" target="_blank">stuck his middle finger up to their cameras</a> (and thus the world).

  • November 2011

    Justin felt the effect of his first paternity suit. He was accused of being the father of a 4-month-old baby boy with Mariah Yeater, but complied with a paternity test and proved his ‘innocence’.

  • May 2012

    It may not sound like a big deal, but in May 2012 a definitely-not-21-year-old Justin confessed to “having a beer” for the first time. Two years later, and he's pretty much a regular in nightclubs (and stripclubs) around the world. In the same month, he also got into an altercation with a tabloid snapper, who reportedly blocked his car in when he left a cinema with Selena.

  • July 2012

    Justin's love of fast cars took a turn for the worse as he was accused of 'reckless driving'. He called 991 to complain about paparazzi chasing him but it turned out he wasn't so innocent himself. <a href="http://hollywoodlife.com/2012/07/06/justin-bieber-speeding-ticket-pulled-over-cops-driving-fisker-karma-paparrazi/" target="_blank">“Bieber was driving like a maniac. He was weaving in and out of traffic. There was hardly any space between cars as he weaved from lane to lane,”</a> an eyewitness, who just happens to be L.A. City Councilman Dennis Zine, said.

  • January 2013

    This image provided by the California Department of Motor Vehicles shows Christopher Guerra, the 29-year-old photographer who was struck and killed while trying to take photos of Justin Bieber's white Ferrari on Tuesday 1 January. Christopher's death spurred renewed debate over the dangers paparazzi can bring on themselves and the celebrities they chase. Justin wasn’t driving his car at the time but it was no doubt a disturbing shock. In the same month, Justin was caught smoking a suspicious looking roll-up cigarette in a pic on a camera phone.

  • March 2013

    The O2 was forced to apologise to young fans after Justin was nearly two hours late on stage for his opening night at the venue. He failed to start his performance until nearly 10.30pm, which resulted in hundreds of fans and parents taking to Twitter to vent their anger. It was a school night, for heavens sake!

  • 7 March 2013

    It all began getting a little 'Michael Jackson' when Justin donned a gas mask (natch) to go out for dinner at Mr Chow in London. The next day he was rushed to hospital after suffering breathing difficulties on stage at London's O2 Arena. Surely the two can‘t have been related?

  • April 2013

    Justin shocked monkeys, fans and animal rights activists when he abandoned his adorable monkey, Mally. The Capuchin monkey was seized by Munich customs when Bieber arrived in Germany as part of his world tour last month, as he did not have the correct paperwork. <a href="http://www.huffingtonpost.co.uk/2013/04/23/justin-bieber-monkey-mally_n_3139497.html" target="_blank">Justin then apparently decided he didn't want him back.</a>

  • April 2013

    We really started to worry about Justin's ego when he speculated that teen Holocaust victim Anne Frank could have been a "Belieber" if she had survived the Nazis. <a href="http://www.huffingtonpost.co.uk/2013/04/14/justin-bieber-hopes-anne-_n_3080439.html" target="_blank">A post on the official Anne Frank Facebook page described his visit to her former house: "Justin Bieber visited the Anne Frank House, together with his friends and guards.</a> "Fans were waiting outside to see a glimpse of him. He stayed more than an hour in the museum. "In our guestbook he wrote: "Truly inspiring to be able to come here. Anne was a great girl. Hopefully she would have been a belieber.""

  • April 2013

    Swedish police confirmed that they had found drugs on board Justin's tour bus. <a href="http://www.huffingtonpost.co.uk/2013/04/25/justin-bieber-drugs-tour-bus-swedish-police_n_3154851.html" target="_blank">Police raided the vehicle after an off-duty officer smelled marijuana coming from the vehicle</a> while it was parked outside the Grand Hotel in Stockholm. This was just the first of many tour bus raids.

  • 17 July 2013

    An Ohio DJ claimed Justin spat in his face while at a nightclub. According to the story reported by TMZ, the pop singer thought the man was taking photos of him. <a href="http://www.huffingtonpost.com/2013/07/17/justin-bieber-spitting_n_3612817.html" target="_blank">The DJ who accused Justin of spitting in his face, Addison Ulhaq, filed a police report against the singer, according to TMZ.</a> He claims he got tested for Hepatitis because the incident left him with saliva in his eye, nose and mouth.

  • 5 August 2013

    Justin was filmed climbing over a car during a nightclub brawl in The Hamptons, New York. The 'Baby' singer came under investigation by the NYPD following the fight at the South Pointe venue in the early hours. 22-year-old Wayne Rennalls was hospitalised after the altercation and suffered a black eye, bruised ribs and a cut lip. He later filed an assault claim. <a href="http://www.huffingtonpost.co.uk/2013/08/08/justin-bieber-hamptons-nightclub-fight-video_n_3724158.html" target="_blank">Footage showed Justin at the scene, however his rep told the New York Daily News: “Justin was not involved in any altercation.”</a> The bust up is said to have started in the roped-off VIP area - where the 19-year-old was seated with his entourage - but ended up in the club's car park.

  • 3 November 2013

    Justin was reportedly smuggled out of a brothel in Brazil during some time off from his tour in the country. According to New York Post's Page Six, the 19-year-old singer and a friend spent three hours in the Centauros brothel in Rio de Janeiro.

  • 5 December 2013

    Justin's potty mouth landed him in a whole load of trouble when his entourage was detained at Brisbane International Airport in Australia on suspicion of smuggling drugs. Beebs was given a <a href="http://www.huffingtonpost.co.uk/2013/12/06/justin-bieber-drugs-brisbane-australia_n_4396840.html" target="_blank">verbal warning for using “inappropriate language” following a conversation with a female customs officer, The Sydney Daily Telegraph report</a>ed. He had allegedly refused to remove his hat and sunglasses during an inspection and also used insulting language toward the officer. Police had to threaten to arrest him, the newspaper said.

  • 14 January 2014

    Move over spurned violinist on Britain's Got Talent, Justin had his own egg-gate when he allegedly egged his neighbour's house, causing $20,000 worth of damage. <a href="http://www.huffingtonpost.ca/2014/01/14/cops-raid-justin-bieber-house-egg-attack_n_4596249.html?just_reloaded=1" target="_blank">Justin was detained in his garage while police with a "felony search warrant" looked for evidence in his home</a> They then arrested his friend Lil Za for cocaine possession during the raid. Bieber has not been connected to the cocaine, but he has been neither charged nor exonerated in the egg incident that promoted the search warrant.

  • 23 January 2014

    All of Justin's troublesome behaviour culminated when he was arrested in Miami Beach for driving under the influence and drag racing. The Miami Beach Police released what is possibly the happiest-looking mugshot in Hollywood's Hall of Shame.

  • 24 January 2014

    Justin didn't forget his admiring teenage fans as he left jail following his arrest for DUI and drag racing. The 19-year-old, wearing a black hoody and dark shades, climbed on top of a waiting black SUV outside the Turner Guilford Knight Correctional Center in Miami to greet his fans before being driven away. And in the process angered a whole load more people.

  • 30 January 2014

    Justin landed himself in even MORE trouble after being charged with assaulting a limo driver. The singer handed himself in at a Toronto police station, where he was mobbed by fans and TV crews. According to the Toronto Police service, <a href="http://www.huffingtonpost.co.uk/2014/01/30/justin-bieber-charged-assault-limo-driver_n_4693256.html?utm_hp_ref=uk-justin-bieber" target="_blank">he will now appear in court on 11 March in connection with the incident, which saw him hit the driver in the back of the head several times last December.</a>

  • 5 February 2014

    Pilots hired by Justin Bieber <a href="http://www.huffingtonpost.co.uk/2014/02/05/justin-bieber-plane-jet-smoking-weed-oxygen-masks_n_4729451.html?utm_hp_ref=uk-justin-bieber" target="_blank">to fly him to the Super Bowl have revealed they had to wear oxygen masks to overcome marijuana fumes on the flight.</a> An official report into the incident also revealed how the troubled teen and his father were “extremely abusive” to a flight attendant.

  • 27 February 2014

    After his arrest footage then emerged of <a href="http://www.huffingtonpost.co.uk/2014/02/27/justin-bieber-arrest-video-singer-stumbles-sobriety-test-pushups-cell-_n_4864217.html?utm_hp_ref=uk-justin-bieber" target="_blank">Justin appearing to sway and stumble as he attempted to walk in a straight line for a sobriety test.</a> The film was shot at a south Florida police station following his DUI arrest in January and reveals the 19-year-old singer also dropping to the ground to do pushups.
