Kourtney Kardashian bared her backside for an artistic series called "Metallic Life" by photographer Brian Bowen Smith. The photos are printed on metallic paper and are on display at the De Re Gallery in Los Angeles through November 19. She's not the first Kardashian to do a professional nude photo shoot, or even an amateur one shot by Kylie on Snapchat. However, Kourtney's picture seems to be all about the art instead of the publicity.
