Chris Brown will perform at next week's Grammy Awards, three years after he attacked then girlfriend Rihanna before the ceremony.

The pair were due to perform together at the event in 2009 but neither turned up after the assault in Los Angeles.

Brown was sentenced to 180 hours community service and five years probation after admitting the attack.

A judge also ordered the R&B star to stay 10 yards (nine metres) away from Rihanna at music industry events.

Chris Brown has not attended the show since 2009 but is nominated for three awards this year including best R&B album for F.A.M.E. (Forgiving All My Enemies).

Rihanna is also scheduled to perform at Sunday's event at Staples Center in Los Angeles. She's up for four awards.

British singer Adele is going to make her live comeback at the event following throat microsurgery last November.

Also performing at this year's Grammys are Sir Paul McCartney, Nicki Minaj and Taylor Swift.

The Grammy Awards will be held on Sunday 12 February 2012
