Heidi Montag wishes she could go back to her old self.

The reality TV star - who has gone under the knife for 10 plastic surgery procedures, including breast augmentation and a nose job - admitted while she wishes she could downsize her chest implants, she doesn't want to go under the knife again.

She explained: "I don't want the biggest boobs in the world and, to be honest, I would take them out and downsize them but I don't want to go under the knife again. I feel like I'm stuck with them now. Sometimes I wish I could go back to the original Heidi.

"I don't want to do that to my body again. I don't want to get any more Botox or any more surgery, or any more lip injections. I think I'm fine the way I am."

The 24-year-old blonde - who recently reunited with estranged husband Spencer Pratt - also confessed undergoing the procedures put a strain on her relationship.

Heidi added to ABC News: "He didn't sign up to be the nurse to his 23-year-old wife at the time, day and night. It was so traumatising what my body looked like. I couldn't look in the mirror. I was hysterically crying and he's like, 'I didn't marry this girl'."
