Heidi Montag, 22, who married costar Spencer Pratt, 25, in April, has been heavily promoting her Playboy spread, going as far as to bring the upcoming September issue where she graces the cover with her on the red carpet for G.I. Joe.

Now the star of The Hills, says she used the magazine as a guide when she got her 2007 plastic surgery. “When I was shopping for my boobs, I wanted the best, so I sat down and flipped through a bunch of Playboys,” Montag, who also had a nose job, gushed to the magazine in an interview conducted by her husband, Spencer.

She’s not done going under the knife in pursuit of her looks either, saying “I plan to get a few more upgrades … I’m sure as I get older I’ll need some touch-ups” adding “I think I want to go bigger on my boobs for [Spencer].”
