The Viacom-owned VH1 cable network is partnering with Ice Cube to launch a hip-hop version of one of TV's longest-running game shows: "Hollywood Squares." Featuring celebrity contestants matching wits and testing their pop culture knowledge in a giant game of tic-tac-toe, the new version will feature the biggest names in hip-hop, comedy and entertainment. Sources say the cable network has ordered at least 20 episodes, which it plans to air in the Fall.
