He started to rapping at the age of 14 by practicing at his local youth group, and released three mixtapes and two promos by the age of 17.
That's quite the work rate.
He's called Chipmunk because when he was a child he was bitten by one and soon took on physical traits… Hang on that was Spider-Man wasn't it.
His first album, 'I Am Chipmunk', did very well thank you very much, producing this Number One single.
The follow-up, 'Transition', which featured a host of American guests, didn't, so there's a message in there somewhere. 'Don't make friends with Changed Man Chris Brown' probably being one of them.
