Heidi Montag has gone under the knife once again. The former Hills star, who made headlines back in 2010 for undergoing 10 plastic surgery procedures in one day, recently went back into the operating room to undo something she'd had done before -- her size F breast implants.
"Sometimes when I'm just sitting there, my breasts hurt so bad, I just wanna, like, rip them off," she admitted to Entertainment Tonight's Brooke Anderson.
Her breasts, which weigh about three pounds each, have caused her a number of serious health problems in the years since she got them. "I have a ruptured disc in my neck, the nerves are pinching my spine, and then I'm having severe back problems with my muscles on my right shoulder," Montag explained. "And my spine is being pulled forward from the weight of my breasts."
Because of these issues -- among others -- the 27-year-old reality TV alum decided to undergo breast reduction surgery to have her existing implants replaced with smaller implants. She's now a size D instead of a size F.
"I do regret getting the implants," she confessed to ET. "I wasn't warned by my doctor at all about back problems, about the repercussions. My new doctor was like, 'You should never have been allowed by the doctor to get implants this big.' I put my security and sexuality in my breast size instead of my confidence."
Asked what she would tell other women considering larger breasts, Montag advised that people should "really think about it" and "really research it."
"They look great, and they sound fun, but once you get them, you've done damage to your skin, to your back, your muscles," she told ET. "Is that vanity worth harming yourself? For me, the answer is no."
Having slightly smaller breasts, she added, is a weight off her shoulders -- and back. "I feel really great," she said after the procedure. "And I'm really relieved that that burden is literally lifted off my chest."
