In companion to her raunchy photos for Playboy, Heidi Montag also has an interview with the publication, during when she admits that she shopped for boobs in the men's magazine before getting her first boob job back in 2007. "When I was shopping for my boobs, I wanted the best, so I sat down and flipped through a bunch of Playboys," she tells husband Spencer Pratt who interviews her, adding "The women are so hot -- Pamela Anderson, Carmen Electra, Marilyn Monroe, all the Playmates."

Greater than that, Heidi claims she's not done making changes to her body and is planning to have more plastic surgery. "The body is a beautiful creation. If anything, the reason I didn't show everything is because I plan to get a few more upgrades", she states. "I'm sure as I get older I'll need some touch-ups. I'm definitely not done with my surgical quest. I think I want to go bigger on my boobs for [Spencer] ... Let's do [another Playboy photo shoot] again when I get the upgrades."

Featured on the cover of Playboy's September issue, which will go on sale Friday, August 14, in addition to doing photo shoot for its inside shots, Heidi claims she hasn't told her father about the photo spread, reasoning "They're a little behind the times where he lives in Colorado, but he'll find out eventually" when referring to her strict Christian family.
