RIHANNA ready to go to court to testify in behalf of ex-lover CHRIS BROWN who had savagely beat her — source.

The Barbadian beauty is ready to go to court to tell the Los Angeles judge handling ex-BF Chris Brown’s felony assault conviction now that he has accepted responsibility and apologized for beating RiRi.

 "Rihanna has spoken to Chris since his progress reporting hearing on Monday afternoon and offered her continued support. Rihanna told Chris she would go to court on November 1 for his court appearance and tell Judge Patricia Schnegg that she shouldn't set a hearing to decide if he violated terms of his probation because he has accepted responsibility for his actions and has apologized to RiRi on multiple occasions," a source told RadarOnline.com.

"Rihanna would also tell the judge that Chris isn't the same person now, as he was on that fateful night when he assaulted her. Rihanna doesn't care if she is criticized for standing by Chris, she genuinely loves him," the source added.

Brown, who remains on probation for the 2009 assault of his ex-girlfriend Rihanna, tested positive for marijuana during a test in Virginia recently.

(News of the positive test was revealed during a progress report hearing on Monday.)

Despite the finding, Los Angeles Superior Court Judge Patricia Schnegg has decided not to immediately find Brown in violation of his probation, but she has scheduled a November 1 hearing to discuss whether she should do so.

Schnegg also ordered that Brown's probation requirements be finished in California because of ongoing concerns with discrepancies about how much community labor he has actually completed.
