Pitch Perfect 3 Exclusive: Hear the Bellas Take On Sia's "Cheap Thrills"!

The Bellas are back in this month's Pitch Perfect 3, and as much as we feel like we can't wait to see the cast reunited, we really can't wait to hear them. The fun of the Pitch Perfect movies is in the songs the group chooses to sing a capella, and they've introduced us to new favorite songs over the years — or totally made old favorites sound new. Case in point is Sia's "Cheap Thrills," which the Bellas perform in the film and which we exclusively have a clip of. Watch the Bellas perform the recent classic and get excited for the release on Dec. 22!
