Some new performances were being added to the 2013 MTV Movie Awards lineup.

While Macklemore and Lewis will debut their new single Can't Hold Us, host Rebel Wilson will join former a cappella teammates for the first live performance from the cast of Pitch Perfect. Wilson will sing with Skylar Astin, Anna Camp, Brittany Snow and the rest of the Bellas and Treblemakers, according to MTV. They will be performing a new mash-up organized by the movie's director, Jason Moore.

Pitch Perfect was nominated for four Golden Popcorns, including Best Female Performance and Breakthrough Performance for Wilson), Best WTF Moment (Camp) and Best Musical Moment.

"I could not be more thrilled for the MTV Movie Awards to be the setting for the Pitch Perfect Bella & Treblemaker reunion," Moore said. "We have something exciting in store for the MTV audience, and I know the cast and the fans are going to really enjoy our first-ever live performance!"

The announcement of the two new musical additions comes shortly after MTV premiered a teaser trailer for The Hunger Games: Catching Fire, which would be featured in its entirety at the Movie Awards. Selena Gomez will also perform with her new single Come & Get It.
