Anna Kendrick Declares Her Love For John Krasinski's Wife on Lip Sync Battle

It was battle of the boy bands in John Krasinski and Anna Kendrick's episode of Lip Sync Battle last night. While Anna made it all about John's wife, Emily Blunt, during her performance of One Direction's "Steal My Girl," John threw it back a few decades — complete with a microphone headset — and performed *NSYNC's hit "Bye Bye Bye." While his dance moves were amazing in their own right, Anna managed to steal the show when she had a video montage of Emily play during her performance, which caused John to completely lose it, laughing as Anna ripped open her top to reveal a t-shirt with Emily's face on it. Check out the hilarious battle above, and then relive Anne Hathaway's headline-making "Wrecking Ball" performance from last week's episode.
