Chris Brown was "letting off steam" when he threw a chair at a dressing room window at a television studio in New York on Tuesday (22.03.11).

The 21-year-old singer - who was sentenced to five years probation and six months community service for assaulting his then-girlfriend Rihanna in February 2009 - claimed he had a meltdown because he felt he was being "exploited" when he was questioned about the incident by Robin Roberts on 'Good Morning America'.

Chris said: "When we actually did this event everything was cool. We were supposed to perform, the talking points were positivity, creativity, and everything that was sent to me, everything was about the album. So as the interview proceeded it was thrown off, I was kind of thrown off by it. I felt like they told us this so that they can just get us on the show just to exploit me. That's what I thought. And so I took it very, very hard.

"I kind of kept my composure throughout the whole interview although you can see me upset. I kept my composure and did my performance and when I got back I let off steam in the back. I didn't physically hurt anyone I didn't try to hurt anyone. I just wanted to release the anger I had inside me because I felt like I worked so hard for this music. And I love my fans and I love to be able to make positive music that I felt like people kept, just trying to take it away from me, take away from me. So yes, I got very emotional and I apologise for acting like that."

However, Chris who is alleged to have been screaming so loudly that worried hair and make-up personnel called security before he ripped off his shirt and leaving the building did apologise and admitted he is "disappointed" in his actions.

In an interview with Black Entertainment Television's '106 & Park', he said: "I want to apologise to anybody who was startled in the office, anybody who was offended or really looked disappointed at my actions because I was really disappointed in my actions

"A lot of people don't know what went down. When I do shows or I do interviews we always send out a talking points sheet and if the network or whomever doing the interviewing isn't complying with what we want to do so we can equally accomplish a goal we usually back out until it's a better situation."
