Chris Brown Won't Be There at Jackson Tribute Concert

Any Chris Brown fans who had hoped to hear the singer doing his best Michael Jackson impersonation at the Sept. 26 tribute to the late King of Pop in Vienna are about to be disappointed.

A rep for Chris' record label has nixed reports that the singer, currently on probation for assaulting former girlfriend Rihanna earlier this year, would be joining acts like Mary J. Blige, Akon and Natalie Cole for the tribute show.

"Chris is not confirmed to perform or participate in any capacity for this show," the publicist told E! News.
