The cast of movie musical Pitch Perfect is to regroup to open the MTV Movie Awards later this month (Apr13).

Rebel Wilson is set to host the ceremony and she'll appear onstage with co-stars Skylar Astin, Anna Camp, Esther Dean and Brittany Snow, among others, for an a cappella showdown, like the one that featured in the 2012 film, which is up for four trophies.

Selena Gomez and MACklemore & Ryan Lewis are also lined up to perform at the MTV Movie Awards.
