The 22-year-old Brown, who's nominated for three awards, is scheduled to perform and attend the show for the first time since his attack on then-girlfriend Rihanna in 2009. He was later charged with felony assault and making criminal threats and took a plea deal of community labor and five years' probation. A year ago, Rihanna's restraining order against the singer was reduced.
Rihanna will also attend the ceremony as a performer and nominee in four categories, including album of the year.
The 54th annual event, hosted by LL Cool J, airs live on Sunday at 8/7c on CBS.
