Chris Brown's Outburst on Good Morning Africa

Chris Brown smashed a TV studio window and ripped off his shirt following an interview in which he was grilled over his assault on Rihanna, according to reports.

The singer flew into a rage after a series of probing questions asked by presenter Robin Roberts on 'Good Morning America'.

Brown played down the incident on the show, saying that the assault was "not really a big deal to me now".

"He went absolutely ballistic," said a source. "Chris thought he'd be asked one question, not pressed on it. He smashed a chair into a window with really thick glass.

"People heard shattering and security was called. It got to the point where people were scared."

After saying they would not press charges, a spokesperson for the show added: "As always, we ask questions that are relevant and newsworthy."

Brown was sentenced to five years probation and six months of community labour in 2009 for assault on Rihanna.  A judge recently commended his probation progress and eased his restraining order which prohibited him from having any contact with Rihanna.
