50 Cent: 'I'm the hardest-working rapper'

Rapper 50 Cent claims he is the hardest working man in hip-hop because he recorded the soundtrack for his new movie while filming it.

The star is so dedicated to the project he spent every moment between takes on the Jim Sheridan-directed Get Rich or die Tryin' laying down tracks.

He says: "I created the music while I was actually filming the movie. I had a studio trailer with me and recorded between takes."
