Chris Brown badly reacted during the interview in Good Morning America's show. Finally the singer has apologized for losing his temper and allegedly smashing a window backstage at a U.S. TV show on Tuesday (22Mar11), insisting he needed to "let off steam" after becoming incensed by questions about his troubled past.

Opening up about the incident during an appearance on Bet's 106 & Park show on Wednesday (23Mar11), Brown claimed he felt ambushed, but is ashamed of the way he handled the fall out.

He said, "First of all, I just wanna apologise to anybody who was startled in the office, anybody who was offended or really disappointed in my actions, because I was disappointed with the way I acted.

"A lot of people don't know what went down, and obviously when I do shows or when I do interviews, we always send out a talking point sheet... As the interview proceeded, it was kinda thrown off. I was thrown off by it. I felt like they told us this just so they could get us on the show so they can exploit me... So I took it very, very hard and I really kinda kept my composure throughout the whole interview, although you can see me upset, I kept my composure, I did my performance.

"And when I got back (stage) I just let off steam. I didn't physically hurt anyone, I didn't try to hurt anyone, I just wanted to release the anger that I had inside me because I felt that I worked so hard for this music and... I felt like people kept just trying to take it away from me. So yes, I got very emotional, and I wanna apologise for acting like that."

And Brown has pleaded with his fans not to take their anger out on presenter Roberts. He added: "Do not send any threats, anything like that, I've been hearing things on Twitter... We need to take a stand and... focus on the more positive things in life."

Actress Samantha Barks was so surprised when impresario Cameron Mackintosh joined her on stage to hand her a role in a Hollywood film. Barks had just finished performing as Nancy in Oliver! at Manchester's Palace Theatre when Mackintosh appeared.

He said she had been chosen to join the cast of Les Miserables, which will also star Hugh Jackman and Russell Crowe. Barks, 21, of Laxey in the Isle of Man, described it as the "happiest moment". She will play the role of Eponine.

She said the news was "still sinking in" and it was the "biggest surprise of my life".

On stage, Mackintosh said he had searched theatres in Hollywood and on New York's Broadway and London's West End to find the actress to cast in the role of Eponine.

Mackintosh said it was "so rare" for a recently unknown performer to make such a quick rise "in our business".

"This is a real rags-to-riches story - a 17 year old who had done nothing when she started out on I'd Do Anything on the BBC," he said.

In 2008, Barks reached the final of the BBC talent show, which allowed the public to choose an unknown actress for the role of Nancy for a new production of Lionel Bart's Oliver!
