Heidi Montag got dirty (literally) on the cover of Playboy this month. She and her husband Spencer seem pretty proud of it, considering they took it everywhere with them last week. Celebrities from Marilyn Monroe to Denise Richards, Kim Kardashian, and Shannen Doherty have graced the pages of the magazine in the past. Would you take off your clothes for Playboy if you had the chance?
