50 Cent video game

YouTube is seeking the next hip-hop star in the US with the help of artists 50 Cent, Common and Polow da Don.

The competition, titled OntheRise Rap Edition, is a follow-up to last year's Underground contest, and according to TechCrunch, three hip-hop stars will judge the acts that enter.

Unsigned artists who have big dreams have until August 17 to submit their demo video to YouTube. The final winner will be announced Sept. 7.
