'Pitch Perfect 2' Star Anna Kendrick Challenges James Corden to a Riff-Off

Anna Kendrick is not one to back down from a challenge. (See her performance on Lip Sync Battle a few weeks back.) So when she appeared on The Late Late Show on Friday (May 15), she was prepared to take on the show's host (and her Into the Woods co-star), James Corden.

Kendrick challenged Corden to a riff-off (timed perfectly with the release of Pitch Perfect 2 this weekend) and shared that "I think this audience wants to see me kick your ass." But, Corden was up for it. With a capella group The Filharmonic assisting each of the competitors, they put their stamp on everything from 'NSYNC's "Bye Bye Bye" to Pat Benatar's "Love Is a Battlefield."

To find out if Kendrick really did kick Corden's behind, watch below.
