Just when you thought Heidi Montag couldn't get any more plastic surgery ...
In the past, the former star of "The Hills" famously had 10 procedures in one day -- including liposuction, breast and butt augmentation and a chin reduction.
But now, she's taking some of it back!
The 27-year-old recently went back under the knife to get her size F breasts (yes, F!) reduced to a size D for health and comfort reasons.
"Sometimes when I'm just sitting there, my breasts hurt so bad, I just wanna, like, rip them off," she tells Entertainment Tonight's Brooke Anderson.
"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."
Heidi has been open about her plastic surgery regrets in the past, something she got into with even more detail.
"I wasn't warned by my doctor at all about back problems, about the repercussions," she says. "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."
So far, she hasn't posed for any new photos yet -- but it's only a matter of time.
