Sneak Peek of the 2007 AMAs

At rehearsals for the 2007 American Music Awards, The Jonas Brothers (Joe, 18, Kevin, 20 and Nick, 15), Chris Brown, T-Pain, Mary J. Blige, Daughtry and Maroon 5 lead singer Adam Levine run through their sets.

Check out Chris Brown’s gravity-defying performance plus a shot of him posing with T-Pain backstage.

The 2007 American Music Awards airs Sunday, November 18, on ABC. We’ll have red carpet coverage and more starting tomorrow.
