Heidi Montag -- who famously underwent 10 plastic surgery procedures in just one day -- won't be going under the knife anytime soon.

She has told she wants bigger breasts, but on The Tonight Show With Jay Leno Friday, she said: "I legally can't right now. The limit is 800cc and I have 700cc.

"I think I've reached the point [where I can stop]," she added. "I think I'm good for awhile. I'm surger-ied out."

Despite her over-the-top operations, The Hills star, 23, denied that she is addicted to surgery.

"I don't think I am addicted," she said. "When you're addicted, you have to do it every day, and thank God I don't do it everyday ... I like to do it all in one day ... knock it out."

She said she is still recovering from the procedures. "It's excruciating," she said, "but beauty is pain."

Montag said her surgery is even the butt of jokes in Just Go With It, the upcoming Adam Sandler comedy she filmed, costarring Jennifer Aniston and Nicole Kidman.

In the movie, Montag (who shot her cameo this week) said Kevin Nealon "has had more surgery than I have ... so we kept playing around with who has more injections."

Montag also opened up about firing husband Spencer Pratt as her manager to hire a psychic. She later axed the psychic as well -- which first reported.

"It just wasn’t feeling right," she told Leno. "I just wanted to be in charge as a woman in my own business. I don’t really want men telling me what to do and where to go so I said, 'You know what? As a woman I’m going to take control of my career.' "
