Chris Brown hit the town last night.
The two attended Jhene Aiko's Sail Out album release party at Space 15 Twenty in Hollywood.
A source who was at the event tells E! News that Brown's mood was "regular, real regular."
E! News exclusively reported on Oct. 29 that the 24-year-old singer had entered an inpatient treatment program to "gain focus and insight into his past and recent behavior."
On Thursday, Brown's rep told E! News in a statement, "Chris Brown is continuing his rehab program as an outpatient and is also completing his community service in the Los Angeles area. He appreciates all of your encouragement and support."
The Grammy winner had checked into rehab for anger management one day after his appearance in court on Oct. 28 regarding an assault charge stemming from a fight that occurred the previous weekend after Brown allegedly punched a man who wanted his autograph.
Brown is scheduled to return to court to answer to a charge of simple misdemeanor assault on Nov. 25 and he must stay away from the alleged victim, 20-year-old Parker Isaac Adams, in the meantime.
