50 Cent scored his first victory as a boxing promoter in Las Vegas on Saturday (December 8), when his SMS Promotions fighter Yuriorkis Gamboa won during the undercard of Manny Pacquiao’s main event bout against Juan Manuel Marquez.

After landing his Nevada promoter’s license last month, Fif’s Cuban fighter earned a unanimous decision over Filipino fighter Michael Farenas.

And… 50 Cent also opened for Gamboa with a performance (above) of his new hit single, “My Life” featuring Adam Levine and Eminem. It will appear on his upcoming album, Street King Immortal, due out soon.
