NICK CANNON
Nick Cannon's prolific career spans the film and television genres. He gained tremendous success as the co-host of "All That," which led to his own cable series, "The Nick Cannon Show." "Nick Cannon Presents: Wild 'N Out" brought hip-hop improv to the forefront and has been nominated for two TEEN CHOICE surfboards since its 2005 premiere. Cannon's next television series, "Short Circutz," will debut next spring. No stranger to the big screen, Cannon starred in the feature films "Drumline" and "Roll Bounce" and had supporting roles in "Bobby" and "Shall We Dance."
