Chris Brown has revealed that he has completed his court-ordered domestic-violence classes.

The US R&B star was required to complete the one-year class after he was convicted of assaulting former girlfriend Rihanna last year.

Brown announced that he had completed the sessions by posting his certificate on Twitter.

"I have enough self respect and decency to be proud of accomplishing this DV class," Brown wrote. "Boyz run from [their] mistakes. Men learn from them!!!"

Brown was also sentenced to six months community labour and five years probation over the attack.
