Pimp C, real name Chad Butler -- and one half of the rap duo UGK, was found dead in a hotel room this morning. He was 33.

L.A. County Fire responded to a 911 call at the Mondrian Hotel, located on trendy Sunset Strip in Hollywood. They arrived to his sixth floor hotel room to find him dead in bed.

UGK is best known for appearing on the Jay-Z track "Big Pimpin'" in 2000, and more recently with Outkast on the song "International Player's Anthem (I Choose You)." Pimp C had just performed with fellow rapper Too Short at the "House of Blues" in L.A. on Saturday night.
