14 August 2009Star of popular TV show The Hills, Heidi Montag has revealed the inspiration behind her breast surgery. The actress, who has posed for the cover of September's issue of Playboy, told the magazine that she turned to it for inspiration when she was planning her breast surgery procedure. She said: "When I was shopping for my boobs, I wanted the best, so I sat down and flipped through a bunch of Playboys. "The women are so hot - Pamela Anderson, Carmen Electra, Marilyn Monroe, all the Playmates. So iconic. "When the magazine asked me to pose I understood what an honour it was. Once you're on the cover of Playboy you're officially a sex symbol." According to MSN news, the 22 year old star, who has also had a nose job in the past, married Spencer Pratt, who also stars in The Hills, in April and revealed that she is planning more cosmetic surgery in the future. She said: "I plan to get a few more upgrades... I'm sure as I get older I'll need some touch-ups." Heidi went on to explain that she did not let herself feel hurt by criticisms of her appearances in the reality show, instead claiming that they proved that she was doing her job properly. She is not the only Hills star to turn to cosmetic procedures however, it's said that Kristin Cavallari has also had a nose job while Lauren Conrad was rumoured to be considering Botox to perk up her appearance earlier this year.
