Macklemore, 'Pitch Perfect' Cast To Perform At MTV Movie Awards!

Host Rebel Wilson and her castmates will reunite for a mash-up performance Sunday, April 14, at 9 p.m. ET on MTV.

Even though the MTV Movie Awards are primarily about the biggest films of the year, they are the MTV Movie Awards, after all, so you had to expect there to be at least some music during the biggest night in Hollywood, right?

Joining Selena Gomez as musical guests for the 2013 MTV Movie Awards will be "Thrift Store" hitmakers Macklemore & Ryan Lewis, who will perform their new single "Can't Hold Us" live on the show, airing 9 p.m. ET on MTV.

As if that weren't enough musical magic to pack into one night, the host of the 2013 MTV Movie Awards, Rebel Wilson, will reunite with her "Pitch Perfect" co-stars for their first live performance onstage. Skylar Astin, Anna Camp, Brittany Snow and the rest of the Bellas and Treblemakers will join Wilson to perform a brand-new mash-up, conceived by "Pitch Perfect" director Jason Moore.

"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 just a day after we revealed that the first trailer for "The Hunger Games: Catching Fire" starring Jennifer Lawrence and Josh Hutcherson would premiere during the 2013 MTV Movie Awards.
