Chris Brown, who assaulted ex-girlfriend Rihanna in February 2009, said that he’s matured into a ‘great guy’. He told Access Hollywood: ‘Everything is good, I’m definitely, me personally and mentally, I’m a great guy now.

I’m more of a person who is definitely more positive. I have new music coming real soon; I’m in the studio, back & forth, continuously, just having fun. I’m going to continue to make great dance videos and just be me.’
