Rapper Kanye West is deadly serious about his obsession with Connect Four - he insists on having the colorful checkers game in his dressing room, so he can use it to help him relax and concentrate before big concerts.

The hip-hop star was recently photographed playing the game with Beyonce Knowles backstage at a show and Connect Four is always on West's tour rider, along with grilled chicken, steamed vegetables, and low-fat potato chips, according to TMZ.com.
