Heidi Montag: A Case of 'Plastic Surgery Addiction'?

May 8, 2010— -- Heidi Montag wants more plastic surgery?

A third breast augmentation may be in the cards for the reality TV star and aspiring singer, according to her husband, Spencer Pratt.

Montag wants to increase the size of her breast implants from 700 cc's to 800 cc's within the next two months, Pratt told Life & Style Magazine.

Pratt says Montag's decision followed an offhand comment by Ryan Seacrest, in which he said that Montag's breasts "didn't look that big." She came home in shock, he told Life & Style, adding that he has tried to keep her away from the plastic surgeon -- with little success.

Pratt's interview comes on the heels of Montag's January confession to a whopping ten cosmetic procedures during one visit to the operating room in November 2010. She had a chin reduction, fat injections in cheeks and lips, breast and buttocks augmentation, and liposuction, among other enhancements.

This built off her 2007 breast augmentation and rhinoplasty.

"I think that it sounds crazier than it looks," Montag told ABC News' Nightline in a January interview, "I think I just look like a different, improved version of myself."

Montag admitted to being "obsessed" before the surgery, spending hours looking through Playboy trying to decide what breast size she wanted, but she denied accusations of being "addicted" to plastic surgery.

"None of those people [that say that] know me at all," Montag told "Good Morning America." "And that's just a judgment. I'm not addicted."

Montag said her enhancements are necessary to help her to succeed in her television and music career. She said she needs sex appeal to make it in this "very cutthroat industry."

Dr. Frank Ryan, Montag's plastic surgeon, defends his patient's choice to purse her various enhancements, saying it's not uncommon in Hollywood.

But when does the desire to surgically perfect oneself go too far? ABCNews.com asked psychologists and plastic surgeons to weigh in on this issue.
