We thought we saw it all when actress Hana Mae Lee wore a cigarette hat on the 2013 MTV Movie Awards red carpet last night but, turns out, we were wrong!

Hana's "Pitch Perfect" co-star and awards show host Rebel Wilson took home the unofficial trophy for craziest outfit when she surprised the audience with a double nip slip (don't worry, it was fake) on stage.

The 27-year-old Australian actress who is known for her scene-stealing role in "Bridesmaids," appeared not to notice her wardrobe "malfunction" at first and then started pointing at it and making jokes.

After she discarded her outfit, Rebel changed into a sexy dominatrix-style ensemble complete with a faux crocodile leather bustier and fur shoulder pads.

Unfortunately, none of the other celebs (except for Hana) put enough effort into their outfits which made for a stale red carpet. (Even Kim Kardashian wore a dress that minimized her baby bump!)

Do you think Rebel's fake nip slip was funny or in poor taste?

Check out all of the red carpet looks from the 2013 MTV Movie Awards and see what your favourite celeb is wearing.

  • Kim Kardashian

    It's true that black is slimming but why does Kim want to hide her beautiful baby bump? Well, we can't really complain since she's been showing if off every day for the past month. The big, billowing sleeves make up for the barely-there bump.

  • Melanie Iglesias

    We didn't know who Melanie was before tonight but she is making sure we won't forget her thanks to this revealing dress.

  • Emma Watson

    She skipped the red carpet but we can forgive Emma because she looks amazing in a watercolour-print dress with a fashion-forward neckline.

  • Zachary Quinto

    We have so much love for a man in a blue suit. So. Much. Love.

  • Kerry Washington

    We love you Kerry but we don't feel the same about your mullet dress. Why is the skirt such an awful shade of yellow?

  • Karina Smirnoff

    A satin peplum does not make for a memorable dress, just a bad one.

  • Seth Rogen, Lauren Miller

    Seth's girlfriend completely shows him up in a cute orange mod dress with adorable pockets. Time to step up your game, Seth!

  • Selena Gomez

    Eat your heart out Justin Bieber! Selena is a golden goddess in a metallic mini dress and fishbraid hair.

  • Kylie Minogue

    Kylie is making a quick stop at the MTV Movie Awards and then heading straight to a disco.

  • Chloe Grace Moretz

    Oh no. Oh no no no no NO. Our 'N Sync denim wish came true and manifested itself onto Chloe Grace.

  • Jordana Brewster

    The white one-shoulder dress is pretty on Jordana but it hits her leg at the wrong spot making her look shorter than she is.

  • Eddie Redmayne

    British style at its best! Eddie is sexy in tailored grey slacks, suede boots and two layers of shirts underneath a leather jacket.

  • Ke$ha

    This outfit is pretty sedate for Ke$ha but she looks like she is on the way to a funeral. Why so serious?

  • Jennifer 'JWoww' Farley

    One word: "Dynasty."

  • Hayley Williams

    Who cares about the outfit when there is that pink and orange hair to stare at?

  • Melissa McCarthy

    Our favourite bridesmaid looks chic in Sinbad-style pants, a three-quarter sleeve top, tons of jewelry and killer heels.

  • Zoe Saldana

    We're not sure why this floral skirt needs a thigh-high slit AND a polka-dot sheer panel but we're not complaining.

  • Claire Julien

    Woah, we've been transported back to the '80s!

  • Macklemore

    Nice... cape?

  • Brittany Snow

    What are those living creatures living on Brittany's shoulders?

  • Kara Hayward

    There's a storm happening in her skirt!

  • Hana Mae Lee

    Don't look up Hana, there's a crushed cigarette on your head!

  • Alexa Vega

    When you can't tell whether an actress is wearing shorts or a skirt, there's a problem.

  • Snoop Lion

    Can we put Snoop on our Best Dressed Ever list yet or is it too early? That red (faux?) fur jacket is everything.

  • RuPaul

    Miss Thang is FA.BU.LOUS. Werk it!

  • Nicole "Snooki" Polizzi

    New mom Snooki of "Jersey Shore" goes glam in a sequined blush gown with a modest slit up the leg. But her hair is having a major attack of the extensions.

  • Holland Roden

    This is a unique twist on the Little Black Dress; it's '50s Betty Draper meets sexy vixen.

  • Quvenzhane Wallis

    The adorable "Beasts of the Southern Wild" actress is toting her favourite puppy purse which she also took to the Oscars.

  • Crystal Reed

    Red lace over nude is a bit last year, non?

  • Ashley Rickards

    What is going on here? Is it a dress? Is it a vest? We are so confused!

  • Sammi Giancola

    We love a sequined chevron dress.

  • Jillian Rose Reed

    Colour blocking can be cool but it just doesn't work on this dress. The shape is awkward.

  • Mike 'The Situation' Sorrentino

    We half expect The Situation to rip his suit off to show off his six-pack.
