Anna Kendrick gives Jennifer Lopez's famous derriere a run for her money in a new preview for Anna's episode of Lip Sync Battle, with John Krasinski. The episode airs tonight on Spike, but the short clip shows just enough of Anna rapping Pitbull's part of "Booty," Jennifer's hit song with Iggy Azalea, to tide us over until then. Anna owns the stage, but when Jennifer walks out in a surprise appearance, both John and color commentator Chrissy Teigen lose their minds. Check out the funny clip, and then look at Anna's other amazing performance all about Emily Blunt and Anne Hathaway's untouchable "Wrecking Ball" performance from last week's episode.
