50 Cent, The Hardest Working 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, according to Contactmusic.

The rapper confessed he spent every moment between takes on the Jim Sheridan-directed "Get Rich or Die Tryin'" laying down tracks. 50's executive produced the soundtrack, which includes brand new music from Mase, Mobb Deep, M.O.P. and 50 himself.

"I created the music for the soundtrack while I was actually filming the movie," 50 Cent said in a statement.

"I had a studio trailer with me and would record every day between takes. I keep telling you, I'm the hardest working man alive", the rapper added.

"Music from and Inspired by the Motion Picture Get Rich or Die Tryin'," the album is due in stores November 8, and features all-new tracks from 50 Cent "and the entire stable of artists on his G Unit Records Imprint," according to a press release.

50 Cent produced the album, Sha Money XL was the co-executive producer and Dr. Dre and Hi-Tek provided further production. Mase, Nate Dogg and newly signed G Unit members Mobb Deep and M.O.P. are also featured on the set.

"Get Rich or Die Tryin" will hit theatres November 9.
