Anna Kendrick Joins Forces With Jennifer Lopez's Booty on Lip Sync Battle

Anna Kendrick gave Jennifer Lopez's famous derriere a run for her money in last night's episode of Lip Sync Battle, with John Krasinski. Anna rocked a choreographed dance routine while performing "Booty," Jennifer's hit song with Iggy Azalea. Anna owned the stage, especially when she rapped Pitbull's part of the song, but when Jennifer walked out in a surprise appearance, both John and color commentator Chrissy Teigen lost their minds. Meanwhile, John pulled out all the stops when he shimmied in a bright sequined dress while performing Tina Turner's hit "Proud Mary." Check out the pair's funny battle above, and then look at Anna and John channeling their favorite boy bands and Anne Hathaway's untouchable "Wrecking Ball" performance from last week's episode.
