Brown 'to perform at the Grammys'
Chris Brown will perform at this year's Grammy Awards, the event where his career almost ended three years ago.
Brown assaulted then-girlfriend Rihanna at a pre-Grammy party in 2009 and is serving five years of probation for the attack.
A source said Brown will hit the stage at Sunday's show. The source spoke on condition of anonymity because Brown's performance has not been officially announced.
After his attack on Rihanna, Brown's reputation plummeted. But he has since bounced back, releasing the multi-hit album F.A.M.E. (Forgiving All My Enemies), which is nominated for three Grammys.
Rihanna will also perform at the show. She is up for four awards.
Brown and Rihanna were supposed to perform at the 2009 Grammys.
