Reality TV star Kim Kardashian insists she hasn’t gone under the knife as yet, but says she won’t mind a surgery for firming up her breasts once she has kids. “It’s crazy that people think I’ve had my nose, cheeks and lips done. It’s just not the case. I’m not against plastic surgery.I will definitely need a boob lift after I have kids. Who knows if I will want to do my face one day,” femalefirst.co.uk quoted Kardashian as saying. The Keeping Up with the Kardashians star, who is dating Kanye West, is known for her curvaceous figure. She says she keeps a check on her diet, but sometimes she finds it hard to resist certain temptations. “When you have curves, you’re just a cheeseburger away from looking heavy. I’m changing the way I eat and it’s a process because I have the biggest sweet tooth,” she said.
