The star-studded line-up at the 2007 American Music Awards has the music world pumped up for one of the hottest nights of the year. Performers on Sunday night's show include Alicia Keys, Mary J. Blige, Celine Dion, Chris Brown, Lenny Kravitz, Fergie, Rihanna, and Duran Duran. Late-night talk show star, popular comedian, and boyfriend-of-Sarah-Silverman Jimmy Kimmel will provide his antics as host once again. With the Writer's Strike in full swing, Kimmel has probably had quite a while to mull over his monologues...This 35th anniversary of the American Music Awards marks the first time the winners will be decided by fans online. Justin Timberlake, Beyonce, Linkin Park, and Daughtry lead the nominees with three nods each.
