London, Dec 4 (ANI): Chris Brown says he never had any “problems with anger” and when he thinks of his attack on ex-girlfriend Rihanna he often wonders how could he do it.

Brown, 20, was arrested in February this after he assaulted the Umbrella singer following a pre-Grammy Awards party in LA.

However, Brown has expressed surprise at his own behaviour.

“I never ever had problems with anger,” the Sun quoted him as saying.

“No domestic violence with any of my past girlfriends or any altercations…”

He continued: “I never was that kind of person… I look at it, and it’s really, really difficult.

“It’s like, ‘How could I be that person?’

“I was wrong for what I did.”

Brown added: “And I would definitely say that it’s not something that I look past or look over.

“Something that’s really, really touchy.

“And, and like I said, I’m really sorry for what went down. And what happened.” (ANI)
