Chris Brown returns to Grammys; Rihanna also to perform

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.
