The rapper, who's been doing his part with his contributions for anti-bullying as one example, is allowing fans to help celebrate the launch of his G-Note record label. The winning bidder and a guest will get to party with 50 Cent at the launch party for his new venture, with proceeds going to the New York Restoration Project. Bidding is open from now until November 22 and fans are encouraged to submit their bid here.

John Legend has his own way of giving back as he's looking to invite fans to sit in on one of his recording sessions in NYC. The winning bidder will get to see the R&B star lay down some brand new tracks. Proceeds from that auction, which lasts until November 15, are going to the Happy Hearts Fund, a non-profit organization founded by Petra Nemcova to aid children who have suffered hardships due to natural, economic and health related disasters.
