Lyric Battle (Grammy Edition): Adele vs. Katy Perry

It's no surprise that Adele and Katy Perry are both scheduled to perform at the 2012 Grammys — they topped the pop charts for pretty much the entirety of 2011! That's why we decided to put these two head-to-head on this edition of Lyric Battle. We're assuming Adele is going to perform "Rolling In The Deep/Someone Like You" and Katy will bust out "Firework/The One That Got Away", but we know you guys have voted for those songs too many times on Lyric Battle. So, we're choosing songs from both artists that we've never featured before: Adele's "Rumour Has It" and Katy Perry's "E.T.". Be sure to check their performances at The 2012 Grammys on February 12th at 8/7c, airing on CBS!

Previously on Lyric Battle, Adam Lambert and David Guetta duked it out for your vote. It looks like you Glamberts pulled through, because the winner was...

Adam Lambert! Here's his winning lyrics:

"If I wanted to leave / I would've left by now / But you're the only one that knows me / Better than I know myself"
