The Pitch Perfect 2 star rests her pipes but gets her exercise as she fiercely takes on One Direction's "Steal My Girl" for Spike's next episode of the relentlessly watchable Lip Sync Battle.
Kendrick doesn't just make a scene for the heck of it, though. In addition to bragging rights, she's fighting to keep the love of one special girl.
And yes, it's Emily Blunt. In this sneak peek right here, watch Krasinski crack up when he sees his wife's picture flash on the screen.
But just when you think that Kendrick is going to run away with this one...
Don't hit stop right when the clip ends. Because is that Krasinski in a sparkly minidress doing Tina Turner's "Proud Mary"? Big wheels keep on turnin'...
Kendrick vs. Krasinski goes down April 16 on Spike TV at 10 p.m.
