A Chris Brown song called "Not My Fault" was recorded three years ago and is not about Rihanna, its producers said. The music appeared online Tuesday, a day after the singer admitted guilt to assaulting Rihanna, his former girlfriend. Brown’s record label also said the music was not “new.” Although Brown accepted a plea deal in which he could avoid jail time, any appearance that he is not remorseful could be damaging, since the judge is not bound by those terms when she sentences him in August.
