R&B superstar turned convicted felon Chris Brown has taken to his MySpace page to tell the public he's truly sorry about his violent assault on Rihanna.

In June, Brown pled guilty to felony assault for the Grammy week altercation with then girlfriend Rihanna. Brown was sentenced to five years probation and six months of community service, hard labor.

Chris confesses, "I wish I could live those few moments again, but unfortunately, I can't." The 20-year-old doesn't "make any excuses" and says, "What I did was inexcusable."

There's been no comment from Rihanna.
