On Thursday, Spike finally aired the full Lip Sync Battle showdown between Anna Kendrick and John Krasinski, and it was every bit as epic as the endless teasers suggested it would be. John started things off with Tina Turner's "Proud Mary," and between his spot-on imitation of her spoken-word intro and his sparkly fringe dress, it seemed like he had a victory in the bag. But then J.Lo showed up during Anna's rendition of "Booty" and it was all over. La Reina didn't even really do anything — she walked out right at the end and just stood there — but that was enough to clinch it for Anna. Once you've got J.Lo on your team, no man stands a chance. Better luck next time, Krasinski.
