March 2009:Brown apologized a week after his arrest. "Words cannot begin to express how sorry and saddened I am over what transpired," he said.

He was formally charged with felony counts of assault and making criminal threats that March 5.

September 2009: Brown and his mother appeared on CNN's "Larry King Live" in his first TV interview since his arrest. "I've said countless times how sorry I am to Rihanna, and I just accepted full responsibility," Brown said.

September 2012: Brown's streak of glowing probation reports came to an end on September 5 when the judge lectured him for testing positive for marijuana use in Virginia.

Brown told authorities he ingested the marijuana in California, where he has a medical marijuana card, according to the judge. Rihanna tweeted to Brown: "I'm praying for you and wishing u the best today!" Brown responded, "Thank u so much." Here Brown appears in court in September 2013.
