Chris may have just finished an anger management programme but he didn't show much restraint on the social networking website with Raz B yesterday.
The incident began after Thornton tweeted: 'I'm just sitting here Thinking how can n—-s like @ebenet & @ChrisBrown disrespect women as Intelligent as @HalleBerry11 [and] @Rihanna.'
Chris responded: '@razb2k, n-- you want attention! Grow up n—-!!! D— in da booty a– lil boy.'
The 21-year-old then continued to tweet several times about Thornton being molested by his ex-manager and one of his former band mates.
Raz B then replied by saying the With You singer was 'down low' - in the closet.
Afterwards the pair both apologised for using homophobic slurs and seemed to have moved on.
Brown later tweeted: 'LOVE ALL MY SUPPORTERS and people who know my heart. HOMOPHOBE?c'mon, find a better tactic.thats pure ignorance and stupidity. i love everyone.'
