Amy Winehouse amyrihanna.jpg We all watched Amy Winehouse tear the house down with her rendition of "Rehab" at the Grammys - and now, it looks like it's going to be the Brits' turn!

The NME has finally confirmed that the troubled songstress will be teaming up with her Grammy-winning collaborator Mark Ronson to perform their cover of the Zutons' "Valerie" on the Brit Awards tomorrow night.

"I heard her rehearse last night and she sounded absolutely great," Brit Awards chairman Ged Doherty told the mag. "We think her performance will be one of those Brit 'moments'."

Of course, Amy won't be the only major artist performing at the Brit awards - heck, she might not even be the biggest collaboration!

Yesterday, the Guardian broke the news that Rihanna would be breaking out another rendition of "Umbrella" - backed up by the Klaxons, one of the hottest bands in England!

The Klaxons, winners of last year's prestigious Mercury Music Prize, are known for the distinctive way in which they mix indie rock and old-school rave music. We can't wait to hear how they interpret "Umbrella"!

Sounds like one crazy pair of performances - which performance are you more excited to see?
