Spencer Pratt and Heidi MontagLeave it to Heidi Montag and Spencer Pratt to use Thursday's screening of 'G.I. Joe: The Rise of Cobra' in Los Angeles as a self-promotion tool. The couple everyone loves to hate walked the red carpet, debuting Montag's new Playboy cover.

The cover shows Montag covered in mud wearing a white bikini and a Playboy bunny logo drawn on her stomach.
