Chris Brown to remain on supervised probation

LOS ANGELES (CBS/AP) - Not so fast, Chris Brown. A judge says the R&B singer should remain on supervised probation despite doing well with the terms of his sentence in a case filed after he beat then-girlfriend Rihanna in 2009.

Superior Court George Lomeli agreed with a prosecutor who said Thursday that Brown should continue to check in at a probation office until after he completes the rest of his community labor.

Brown has finished half of the six months of community service he was ordered to perform after pleading guilty to the attack that occurred the night before the Grammy Awards in 2009.

Speaking of the Grammys, Brown will return to the Grammy stage on Sunday. He will perform as part of a dance/electronica set with deadmau5, Foo Fighters, David Guetta and Lil Wayne. Rihanna will also be at the event, performing with Coldplay.

As for Brown, he's keeping a positive attitude. "Understanding possibilities are endless once u put forth the effort with confidence! BE FREE ....," he tweeted Thursday.
