Watch Anna Kendrick Lip-Sync “Booty” With a Surprise Guest

John Krasinski’s Tina Turner impression had nothing on this.

Another week, another round of very famous people moving their mouths in coordination with popular music. This week, on “Lip Sync Battle,” Anna Kendrick destroyed John Krasinski with an impassioned rendition of Jennifer Lopez’s “Booty.”

Krasinski put up a strong fight, channeling his inner Tina Turner for “Proud Mary” (a favorite karaoke song of mine, even though I still maintain the stance that karaoke is a more noble activity than this). But Kendrick kicked ass, especially with her secret weapon: an appearance from J. Lo herself.
