Chris Brown is scheduled to appear in a Los Angeles courtroom to update a judge on his probation for his 2009 attack on Rihanna.
Wednesday's hearing is the first time Brown has been in court since he was arrested last month in Washington, D.C. A 20-year-old man accused Brown of punching him after he tried to get in a photo with the R&B singer.
Brown denied to police that he hit the man but was charged with misdemeanor assault.
Since then, the Grammy-winner has entered and left rehab for anger management treatment.
Brown's probation for assaulting Rihanna was briefly revoked this summer after a hit-and-run incident. He was also ordered to redo 1,000 hours of community service because there were questions about whether he actually completed his initial penalty.
