Heidi Montag plans to risk her life again with another surgery, Life & Style can exclusively reveal. Heidi's husband Spencer Pratt tells Life & Style she wants to increase the size of her breast implants from 700 cc's to 800 cc's. "She wants to do it within the next two months and film it for the new TV show she and Spencer have been pitching to cable networks E! and Oxygen," an insider says. Even crazier? Heidi's looking to have the surgery done in Europe, not by an American-board-certified doctor! Spencer insists he's already doing everything he can to keep her away from her plastic surgeon -- and it's no easy task. "I try to stop her," Spencer tells Life & Style. "She wants her doctor to come over once a week to plump up her lips. I keep telling her that they're big enough and that she doesn't need it."

So what put her over the edge? Spencer tells Life & Style about an off-the-cuff remark from Ryan Seacrest during a visit to his LA radio station on April 5 that shattered Heidi's world. "When Heidi entered the studio, Ryan told her that her breasts didn't look that big to him," Spencer, who was standing just a few feet from his wife at the time, says. Although Ryan's comment was clearly meant to compliment Heidi and calm any preshow jitters she may have had before her early morning interview, his words took on a twisted meaning in her mind. "She was taken aback," Spencer says. "She came home in shock." The incident just confirmed the outrageous fear she'd had since undergoing her latest round of plastic surgery in November: that her breasts still aren't big enough.
