London, Dec 7 - Singer Chris Brown says he was shocked by his own violent behaviour in the bust-up that ended his romance with Rihanna as he has never lost his temper so badly before.

"I never ever had problems with anger. No domestic violence with any of my past girlfriends or any altercations. I was never that kind of person. Today, when I look at it and I ask myself - 'How could I be that person?'," starpulse.com quoted Brown as saying.

"I was wrong for what I did and I would definitely say that it's not something that I look past or look over. Something that is really touchy. I am sorry for what went down and what happened," he added.

The singer was arrested in February after he assaulted Rihanna in a vicious fight following a pre-Grammy awards party.
