Brown explains reasons for dressing room tantrum

Chris Brown was “letting off steam” when he threw a chair at a dressing room window at a television studio in New York last Tuesday.

The 21-year-old singer, who was sentenced to five years probation and six months community service for assaulting his then-girlfriend Rihanna in February 2009 – claimed he had a meltdown because he felt he was being “exploited” when he was questioned about the incident by Robin Roberts on 'Good Morning America'.
