WATCH: Anna Kendrick Steals John Krasinski’s Wife Emily Blunt on ‘Lip Sync Battle’

We bet you didn't know THIS about Anna Kendrick

Move over, Zayn Malik.

Anna Kendrick and John Krasinski duked it out on last night’s episode of Lip Sync Battle on Spike TV.

The Office star channeled his inner J.T. with a marionette-esque performance to “Bye Bye Bye.” Kendrick retaliated with One Direction’s “Steal My Girl” as a slideshow of her competitor’s wife, Emily Blunt, played on the backdrop. The 29-year-old then opened her leather jacket, revealing a personalized t-shirt of herself and Blunt encompassed by a heart. Boy bands FTW.

The second half of the show kicked off with Krasinski as Tina Turner, shaking his romp in a flapper dress. The performance was undoubtedly sensational but yet again, Kendrick stole the stage by element of surprise. Zilch the personalized tee, she dropped J-Lo right into the middle of her routine.

The Pitch Perfect actress said, “Why I decided to sing a song about booty, on the same stage as J-Lo’s booty, I will never know.”

Acknowledging his defeat, a bewildered Krasinski exclaimed, “Wait, wait, wait, what is happening?!”
