Chris Brown turns violent

TMZ reports that singer Chris Brown turned violent on the "Good Morning America" show in New York City.
Apparently Brown was on the show to promote the release of his latest album F.A.M.E.
According to TMZ he became too uncomfortable when the questions continually diverted away from his album and onto his infamous physical altercation with ex-girlfriend Rihanna.
A person familiar with the show says Chris Brown trashed his dressing room and broke a window with a chair after co-host Robin Roberts asked him about his attack on Rihanna.
Security was called, but not police.
Roberts, asked him about the 2009 attack on his then-girlfriend. An agitated Brown tried to deflect the questions and said: "I'm past that in my life."
After the interview, Brown performed.
Reps for Brown did not immediately return phone calls for comment.
Brown later tweeted: "I'm so over people bringing this past s**t up!!! Yet we praise Charlie sheen and other celebs for there bulls**t."
He later took down the tweet and wrote "All my fans!!! This album is for you and only you!!! I'm so tired of everyone else!! Honestly!! I love team breezy!!"
Brown is on probation for his assault on Rihanna.
