Chris Brown and Rihanna are together again and there's nothing anyone can say or do about it.

That doesn't mean the young singer isn't remorseful about what made the pair break up in the first place.

"The deepest regret of my life, the biggest mistake," he told the Mirror (via The Huffington Post] of assaulting Rihanna the night of the Grammy Awards in February of 2009. But the couple have moved on from that.

"Sometimes you row, you fight, with the one you love and things get said, stuff spirals," he said. "But she loves me – what can I say? I'm forgiven... but, yes, I worked hard for it."

This, of course, is the same song Brown has been singing since 2009.

Is it us who can't let it go, or him?
