London, May 6 (Inditop.com) Reality television star Heidi Montag, who is obsessed with attaining a perfect body, is set to go under the knife for the 11th time after a massive cosmetic makeover.

“She wants to do it within the next two months and film it for the new TV show she and husband Spencer Pratt have been pitching,” contactmusic.com quoted a source as saying.

Pratt said: “I try to stop her. She wants her doctor to come over once a week to plump up her lips. I keep telling her that they’re big enough and that she doesn’t need it.”

The source also revealed Montag wants to increase the size of her breast implants from 700 cc’s to 800 cc’s.

The 23-year-old has previously admitted to having a nose and breast job, but she has had various plastic surgery procedures done since Nov 20, including breast augmentation, liposuction, butt augmentation, nose job revision and botox.
