Pimp C, one-half of the veteran Houston rap group UGK, was found dead in an upscale hotel on Tuesday. "It is with great regret that I must confirm that Chad Butler aka Pimp C, one half of the legendary UGK, was in fact discovered dead this morning," his publicist, Nancy Byron, said in a statement. "Manager Rick Martin is asking that everyone please respect his family and those close to him at this time and refrain from rumors and innuendo." Pimp C and partner Bun B were pioneers of Southern rap, and hit the mainstream with their cameo on Jay-Z's hit "Big Pimpin'."
