Watch out Prince Harry!

Wearing a bejeweled gold crown, Katy Perry looked as if she were gunning for a royal title at the 2013 Met Gala in New York on Monday in a Dolce & Gabbana look complete with a Byzantine-inspired frock with hand-sewn beaded bronze, gold and turquoise mosaics.

The designers, Domenico Dolce and Stefano Gabbana, were inspired by the island of Sicily and the mosaics of the twelfth-century cathedral in the city of Monreale.

The "Firework" singer completed the look with extravagant gold cross earrings, ornate rings and black and gold heels.

This isn't the first time the 28-year-old channeled her inner princess. Katy wore a Marie Antoinette-inspired gown AND sat on a massive throne while promoting her third fragrance "Killer Queen" in early May. (She would definitely give Kate Middleton a run for best-dressed.)

Perry wasn't the only celeb to channel the late French Queen; former reality star Nicole Richie dyed her hair grey just as the royals did in the 18th century.

It's a royal takeover!

  • Beyonce

    All hail Queen Bey! Her dress really does look like it's on fire.

  • Beyonce

    From the front! Matching boots and a thigh-high slit, yes please!

  • Kanye West and Kim Kardashian

    Stop the presses: Kimye has arrived! Anna Wintour lifted her Kardashian ban and let Kim attend the Met with baby-daddy Kanye West. We're a bit disappointed that Kim didn't rock out with some studs or at least some hair dye. Florals, Kim? For spring? Groundbreaking.

  • Miley Cyrus

    The singer takes punk RAWK to the max in a sexy nude gown with a sheer, fishnet overlay and her short hair spiked up. Rock on!

  • Katie Holmes

    Katie's revenge outfit! Tom Cruise's ex is a Grecian goddess in this simple halter gown.

  • Katie Holmes

    We had to give you a better photo of Holmes' dress so you can see the long, layered train. But what's with her odd bouffant?

  • Katy Perry

    Katy's a Byzantine princess!

  • Kristen Stewart

    A THOUSAND TIMES YES TO KRISTEN STEWART. A red lace jumpsuit that puffs out at the waist? Only the lithe "Twilight" actress could pull this off. But where's Robert Pattinson and his pout?

  • Jennifer Lawrence, Sarah Jessica Parker

    This is the best photo we've ever seen! "The Hunger Games" star looks like she's wearing a mourning dress and having the time of her life while SJP is wearing an elaborate fauxhawk. We love the Met Gala!

  • Taylor Swift

    This metallic and black gown is pretty punk for Taylor Swift. Look, she made her hair all wavy in tribute!

  • Greta Gerwig

    The "To Rome With Love" actress looks as if she belongs on the set of "Downton Abbey" not at a tribute to punk couture.

  • Aubrey Plaza

    We can definitely picture the "Parks and Recreation" actress party backstage with Sid and Nancy in this fabulous snakeskin cape dress.

  • Heidi Klum

    Guess the model didn't read the "No Boring Strapless Dresses Allowed" rules.

  • Bella Heathcote

    Maybe the actress is channeling her English roots into a more modest punk interpretation.

  • Jaime King

    If punk met the office than the model would fit right in.

  • Amber Heard

    Johnny Depp's maybe-girlfriend and actress Amber Heard takes the safe route in a vintage-looking red gown.

  • Constance Jablonski

    Models normally can pull off any look but Constance needs to try again.

  • Chloe Sevigny

    The "Big Love" actress nails it in a sheer lace number with a head turban. It's more of a modern take on punk.

  • Nina Dobrev

    Is that our little Canadian TV star, Nina Dobrev? The "Vampire Diaries" actress is sizzlin' in a sheer hoop skirt and lace applique nude jumpsuit.

  • Uma Thurman

    We love the origami-inspired green frock on Uma but we think it's more suited for the Oscars. Let's see some more risk-taking, Uma!

  • Lauren Bush Lauren

    The model/designer (who is also George Bush's niece) falls a bit flat in this pretty but boring black lace gown.

  • Dakota Fanning

    The "New Moon" actress is all grown up in a sexy black gown with sheer cut-outs and what looks like embroidered wings flanking her waist. HOT.

  • Lauren Santo Domingo

    The Vogue contributing editor channels the dark, gothic underbelly of punk and perhaps a nod to Scarlett O'Hara.

  • Jennifer Morrison

    The "Once Upon A Time" actress is goth glam in this majorly sexy black tulle gown and a spikes fauxhawk.

  • Dylan Lauren

    Dylan has fashion running through her veins (her father is designer Ralph Lauren) so why is she wearing such a boring dress??

  • Ivanka Trump

    A Donald Trump offspring was actually allowed to dye their hair!!

  • Rooney Mara

    The "Girl With the Dragon Tattoo" star is this year's Met Gala co-chair and she takes the job seriously in a white lace gown with a frilly slit and exaggerated shoulders. The zippers on the waist are punk, right?

  • Nora Zehetner

    Who knew that Dr. Reed (of "Grey's Anatomy") could dress so well? So the Indian sari isn't punk, whatevs, it's still gorgeous.

  • KarolĂ­na Kurkova

    We think the model channeled a bit too much punk here.

  • Bee Shaffer

    When your mom is the editor-in-chief of Vogue magazine, you would think that you'd have more dress options to choose from, so why did Bee wear such a blah gown?

  • Amar'e Stoudemire and Alexis Stoudmire

    The New York Knicks forward and his wife are unofficially the best-dressed couple of the evening.

  • Zandra Rhodes

    Can't you tell that Zandra is an English fashion designer? She LIVED punk back in the day.

  • Anja Rubik

    The model has legs for days...

  • Anna Wintour

    We're too afraid to say anything about Anna's dress for fear she will send us to find the unwritten eighth Harry Potter manuscript.

  • Lindsey Vonn and Tiger Woods

    The World Cup skier and champion golfer are dating, and they aren't afraid to show it!

  • Emma Roberts

    We were really hoping that the actress would wear her aunt Julia Roberts' "Pretty Woman" hooker costume.

  • Emilia Clarke

    We're not sure what the "Game of Thrones" actress was going for with this fire-red gown (maybe it's a nod to the Khaleesi's dragons?) but we wish she used her imagination to find a better dress.

  • Diane von Furstenberg

    One can never tell the American fashion designer what to wear. Diane is always in Studio 54 mode.

  • Elle Fanning

    We don't know what to say about the actress' dress because we are sucked into the tie-dye hole that's hypnotizing us..

  • Ashley Olsen

    Who's that? Oh just multi-millionaire/sometimes actress Ashley Olsen who just floated down from her penthouse to say hello.

  • Giovanna Battaglia

    Help! The L'Uomo Vogue editor is stuck in a bee hive!

  • Kerry Washington

    Mesh, leather gloves and floral. The "Django Unchained" actress is the epitome of punk rock chic.

  • Jessica Alba

    Ok guys, we're a bit tired of seeing all this black lace.

  • Karlie Kloss

    Ooohhh we love this vintage-inspired satin dress on the super hot model du jour.

  • Coco Rocha

    Canada represent! The B.C.-born model knows that leopard is basically the foundation of punk couture.

  • Amanda Seyfried

    We don't quite get the "Les Miserable" star's inspiration but we still dig it.

  • Kirsten Dunst

    There goes our Kiki being all quirky again.

  • Kate Mara

    It's Zoe from "House of Cards" a.k.a. our favourite show! We don't want to get too close to the actress because we're afraid her spiked dress will literally kill us.

  • Solange Knowles

    Punk needs more rockers with 'fros.

  • Kate Beckinsale

    This is what we're going to say about the "Underworld" actress' dress: It's nice.

  • Nicki Minaj

    Is this the wacky singer we know and love? Where is she?? Who is this sedate run-of-the-mill woman who replaced her?
