The Crazy Moment: In late March, Chris Brown let his temper get the best of him during a Good Morning America interview. After Robin Roberts asked him several Rihanna-related questions, he stormed off the GMA stage, reportedly threw a chair through a window in his dressing room, and left the building without a shirt on.
Our Reaction: C'mon now, Chris! We know you don't like being asked questions about Rih-Rih, but you had to know they were coming, right? This incident made you look bad and gave people a reason to bring up the whole Rihanna thing again, which is exactly what you were trying to avoid in the first place. This was easily your worst moment of 2011.
