Anna Kendrick, John Krasinski bring their A game to "Lip Sync Battle"

Anna Kendrick and John Krasinski battled it out Thursday in another hilarious round of Spike TV's "Lip Sync Battle."

Let's just say, it involved bootie shaking by Kendrick, a surprise visit from Jennifer Lopez and glittery dress worn by the former "Office Space" star.

Krasinki took on *NSYNC's "Bye Bye Bye," while Kendrick managed to incorporate Kendrick's wife, Emily Blunt, into her routine. Blunt, though, outshone Krasinski, according to audience reaction.

Check out a couple of their performances below:
