Trouble Offaiah Download 'Trouble' on iTunes
His MC name is MC Nicky J, his family have nicknamed him 'Shaan' - put them together and you get Jay Sean.
Jay first grabbed the mic and started rapping at the age of eleven, in a hip hop duo called 'Compulsive Disorder' with his cousin MC DNA (we're guessing that's probably not his real name either).
He grew up and went to a private boys school in London and then moved on to college, where he trained as a doctor for two years before giving it all up to pursue his music career.
Jay's hits to date include 'Dance With You', 'Stolen' and 'Ride It' and now he's back again with his new single, 'Tonight'. Hoping to break the US market with this one too, he's teamed up with Lil Wayne who has remixed the track.
Take a look at the video for 'Tonight' and let us know what you think.
