Rebel Wilson hosted the 2013 MTV Movie Awards on Sunday and in a comedic effort to introduce herself on stage, she wore a padded costume that revealed a faux double nip-slip.

She wore a black cut-out dress and pretended as if she has no idea what she was revealing when she spoke to the audience. The audience roared with laughter and Wilson asked sarcastically what they were laughing about. See photos here.

The Pitch Perfect star took to the stage at Sony Pictures Studios in Culver City, Calif., and opened the show with a performance. She reunited with her film's co-stars for an original musical mash-up. The group performed versions of Eminem's Lose Yourself, Miley Cyrus' The Climb, Alicia Keys' On Fire, Macklemore & Ryan Lewis' Thriftshop and more.

On Sunday Wilson won Breakthrough Performance for her role in the film and along with her co-stars they took home the award for Best Musical Moment. Pitch Perfect is about a freshman (Anna Kendrick) at Barden University who is convinced to join the school's all-girls singing group, The Bellas. Together they take on their male rivals in a campus competition.

Wilson will lend her voice for 2015's animated film Kung Fu Panda 3.
