Justin Bieber is gonna have to do a lot more than say he's sorry to get out of this one!
Yikes! This could get ugly.
Take a listen to both songs (below) to hear the very recognizable riff!
Emma Stone is superior to them all!
First, she pulls out an AH-MAZING Blues Traveler song and then she surprises EVERYONE with her last song choice and BRILLIANT performance.
And we had TOTALLY thought Jimmy was sure to win with that rendition of Fancy by Iggy Azalea!
We were SO wrong.
What are you waiting for?!?! Press play and watch the best lip sync battle yet (above)!
COME ON! Just look at her moves!
