Chris Brown will perform at this Sunday's Grammy Awards for the first time since beating his then girlfriend Rihanna in 2009 on the eve of the music industry's biggest night, which threatened to derail his music career.

Rihanna also is among the stars performing live at the event, and rumors have flown among fans and celebrity watchers in recent weeks that the pair may be secretly dating again, speculation Brown's representatives have dismissed.

Grammy organizers said Tuesday that Brown, who has three nominations including best R&B singer for his album F.A.M.E., had been added to the line-up for the February 12 awards show in Los Angeles.

They said Brown will join Foo Fighters, Lil Wayne, David Guetta and deadmau5 for a performance highlighting dance and electronica music for the first time on the Grammy Awards show stage.

Rihanna, who has four nominations including album of the year for Loud, will sing with Coldplay on the Grammy stage.

Brown, 22, has skipped the Grammys since launching a violent attack on Rihanna in 2009, leaving her battered and bruised and Brown in the custody of police.

He publicly apologized and admitted to criminal assault in court. A judge sentenced him to five years probation, six months community service and anger management.
