Chris Brown has not signed up to lead the musical tribute concert to Michael Jackson in Vienna, Austria - despite the pop icon's brother Jermaine backing him as the main headliner.

At a press conference in the European city on Tuesday, The Jackson 5 singer told reporters that disgraced Brown would take center stage at the star-studded tribute for the late "Thriller" legend on September 26.

He confirmed, "Michael was his idol and he (Brown) dedicated his first number one hit in the U.S. to Michael. Chris is a very, very talented artist."

It was to be Brown's first time on stage since his brutal attack on ex-girlfriend Rihanna in February. He was sentenced to five years probation and six months hard community labor last month.

And although Brown obviously has the support of the superstar clan, a rep for the shamed singer insists the "Kiss Kiss" hitmaker's appearance at the show has not been scheduled.

The spokesperson says, "Chris is not confirmed to perform or participate in any capacity for this show."

Other artists on the bill include Mary J. Blige, Natalie Cole and Sister Sledge, as well as American boyband US5.
