Amy Winehouse will perform during this year's Grammy ceremony despite being denied a visa. Thanks to the wonders of technology, Winehouse, who is currently encamped in a U.K. rehab center, will perform live in a London studio the night of the awards show, with her performance being beamed to Los Angeles and around the world via satellite. "I'm raring to go and really excited to be performing at my first Grammy Awards," Winehouse tells Usmagazine.com. "I'm really sorry I can't be there but I appreciate that I'm being given a second chance via satellite." Also performing at the Grammys (though not yet officially confirmed) is Kanye West, who was seen rehearsing for the ceremony yesterday afternoon. West, nominated for eight awards, will reportedly perform a medley of tracks including "Hey Mama" as a tribute to his mother Donda.
