Chris Brown is to stay in rehab for further anger management treatment after completing his 90-day court-ordered stint, according to a U.S. report.

A judge ordered the troubled singer into rehab in November (13) for temper therapy amid mounting legal troubles, including having his probation stemming from his 2009 assault on his pop star ex-girlfriend Rihanna revoked.

Brown's treatment finished this month (Feb14), but a judge has ruled he should remain in rehab to receive further help, according to E! News.

The Kiss Kiss hitmaker was reportedly given a pass to leave rehab on Friday (21Feb14) to collect an award from a Los Angeles-based community group. He documented his evening in a series of posts on his Instagram.com page and later announced plans to release a new album in May (14).
