Chris's temper explodes again

Chris Brown -- Violent Outburst at 'GMA'
46 minutes ago by TMZ Staff

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.



ABC sources tell TMZ ... Brown performed and was interviewed by Robin Roberts live from the Times Square studio when she began asking about the infamous incident.



Brown tried to redirect the questions to focus on his album -- but Roberts continued to ask about Brown's legal issues stemming from the Rihanna incident.



We're told 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.

We're told Brown was out of control, and one source present tells us he smashed a window in his dressing room, and the glass shattered and some shards fell onto 43rd and Broadway. ABC security tells TMZ ... the window was shattered with a chair.

We're told 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 for the ABC website.

And sources say ... on his way out of the building, Brown confronted a segment producer, got in his face and stared him down. People from the show got in between Chris and the producer to diffuse the situation.

Remember -- Brown is on probation for the felony beating and he's required to obey all laws.

UPDATE 6:49 AM: Brown just tweeted, "I'm so over people bringing this past s**t up!!! Yet we praise Charlie sheen and other celebs for there bulls**t."

UPDATE 6:59 AM: Brown has already deleted the previous tweet ... and added a new one that reads, "All my fans!!! This album is for you and only you!!! I'm so tired of everyone else!! Honestly!! I love team breezy!!"

I respect Robin Roberts as a reporter, but it was tacky for her to keep bring up Rihanna....twice.....when Chris obviously didn't want to talk about it. That's some shit Wendy Williams would do. This boy is trying to put his career back on track, he don't wanna hear about no damn Rihanna and he shouldn't.
