Chris Brown didn't have his best day today - After a tense interview with American journalist Robin Roberts on 'Good Morning America' and a subsequent scheduled performance, Chris Brown exploded in rage behind the scenes and even smashed a window in his dressing room. Why? Well, during the interview Robin Roberts reminded Chris about the Rihanna episode (something that 'happened two years ago', quickly responded Brown), the restraining order's status, the relationship he has now with Rihanna, etc...Robin kept asking and Chris kept avoding a clear answer and said he was there to promote his new record 'F.A.M.E'. You could cut the tension with a knife! After the interview was over, Robin introduced Chris Brown on stage where he performed his dance-pop hit "Yeah 3X". He looked angry! The dancing was cool but the vocals! OMG. That auto-tune mic....SMH. Mess.
