Chris Brown spent the evening after he was sentenced for assaulting Rihanna at a Los Angeles nightclub, where he gave a rendition of Michael Jackson's 'Dirty Diana'.
The 20-year-old singer - who received six months community labour and five years probation after pleading guilty to the February attack - was at Hollywood nightclub Guys and Dolls on Tuesday evening (25.08.09), where he gave an energetic rendition of Michael's hit 'Dirty Diana'.
An onlooker said: "He stood up on the back of the booth when the song came on, got a mic and not only sung, but danced his a*s off. He didn't seem to care at all that everyone was watching him. He was in a totally good mood, just hanging out with his buddies. Then all of a sudden he decided to put on a little show."
After his performance, Chris said: "There was only one 'King of Pop'. We love you, Michael."
For his 1,400 hours community labour, Chris - who punched, bit and choked his on/off girlfriend in his car on February 8 - will have to remove graffiti and wash cars.
He was also ordered to go to domestic violence classes for a year and is not allowed to contact Rihanna for five years.
Chris has to pay fines and will have to undergo random searches and seizures.
Meanwhile, it has been claimed Chris has recorded a no-holds-barred interview with US talk show host Larry King, in which he is quizzed about the assault.
The interview is set to be aired next week.
