Chris Brown is extending his stay in rehab.

The "Fine China" singer recently completed his court-ordered 90 days in a treatment facility in a bid to overcome his anger management issues but has decided to stay there for further treatment.

"It was his choice. He will come out soon," a source close to the 24-year-old singer told E! News.

The star voluntarily checked himself into rehab in Malibu, California in October after being accused of assaulting Parker Adams, who is suing the singer and his bodyguard for $3 million, in Washington D.C., but he was kicked out after throwing a rock through his mother Joyce's car window. The R&B singer was then ordered to seek anger management at a different facility instead of being sentenced to jail when his probation, stemming from his violent assault on then-girlfriend Rihanna in 2009, was formally revoked as a result of the alleged assault.

Chris and his bodyguard's criminal trials are set to begin on April 17. The "Forever" hitmaker has been granted permission to leave rehab to attend several events recently, including a celebration to honor his work with LA community group 2nd Call and his Symphonic Love Foundation and Unity Campaign on Friday night. A source said he stayed for more than two hours, appeared to be in "good spirits" and warmly greeted people who came to his table.
