The 29-year-old star took a cue from her new movie, Pitch Perfect 2, and challenged the host of The Late Late Show to a live riff-off on Friday.
Kendrick, wearing a track jacket bearing her name, interrupts Corden, entering the talk show set ready for battle.
“I heard you’ve been telling people that you’re the best acapella singer in town,” Kendrick says, before challenging the host to a riff-off. “I think this audience wants to see me kick your ass.”

The sing-off continued with themed categories until Kendrick took the lead with an impressive version of Pat Benatar’s “Love is a Battlefield.”
In the end, the Into the Woods costars decided to band together to sing the last medley, a pairing of Vanilla Ice’s iconic “Ice Ice Baby” and Katrina & The Waves’s “Walking on Sunshine.”
