Chris Brown went nuts, smashed a window on GMA

The last time we saw Chris Brown, he was telling the New York Post that he's a grown ass man and was done apologizing for beating up Rihanna. He said it was a "mishap", a one time thing, punching a woman in the face was just a phase, like fubu jerseys, and he was over it. He even said...

"...you can't walk around mad, because then you just prove everybody right that you're an angry person."

So Chris Brown isn't violent or angry anymore, and if you question him about it, he'll get angry and smash all your shit.

Chris Brown exploded in rage behind the scenes at "Good Morning America" this morning ... smashing a window and storming out without a shirt ... Sources tell TMZ ... and it was triggered by on-air questions about the Rihanna incident.
Brown performed and was interviewed by Robin Roberts when she began asking about (Rihanna). 
Brown tried to redirect the questions to focus on his album -- but Roberts continued to ask about (Rihanna).
...after the interview, Brown freaked out, storming into his dressing room and screaming so loud, the people in hair and makeup became alarmed and called security.
...he smashed a window in his dressing room, and the glass shattered and some shards fell onto 43rd and Broadway.
…by the time security rushed the area, Brown had ripped off his shirt and left the building, blowing off another performance he was supposed to do.

Brown is still on probation, so if this really happened as its being reported and police get involved, he's in serious trouble, as he should be. In Browns defense, that window had been talkin shit all morning. Not so tough now are you, window! Who's the man now, shirt!
