chris brown GMA violentChris Brown was confirmed to perform on 'Dancing With the Stars' next week, but after a violent incident this morning at ABC's 'Good Morning America,' several top executives are demanding the 21-year-old singer be banned from ABC.

"Chris was so dangerous backstage that we called 911," a 'GMA' insider tells me. "He totally flew off the handle after being asked a question about his 2009 assault of his then-girlfriend Rihanna. Now ABC has to decide if they are willing to let this man promote his music on a family show on its network or walk away from this obviously troubled young man."

During the 'GMA' interview to promote the release of his new album, 'F.A.M.E.,' Brown told anchor Robin Roberts, "It's not really a big deal to me now, as far as that situation. I think I'm past that in my life. Today's the album day, so that's what I'm focused on."

Brown went on to perform a song before returning to his dressing room and tearing it apart.
