Kim Kardashian is reportedly not able to go under the knife for any plastic surgery because Kanye West is afraid of potential risks. While it has long been speculated that the reality star has had surgery to enhance certain body parts, her boyfriend is not letting her do it again.

“Kim was certain that she wanted to have surgery after giving birth because she wanted a head start on losing her baby weight,” a source tells RadarOnline. But West was completely against it. “He really flipped out.”

The 36-year-old rapper has a reason to not let his girlfriend have cosmetic procedures. In 2007, his 58-year-old mother, Donda West, died from surgical complications following a tummy tuck and breast reduction.

“Kanye told Kim in no uncertain terms that she needed to put her baby and her life first,” the source continued. “He got pretty emotional because he really didn’t want her going through that kind of major surgery.

He’s still traumatized by his mom’s death. It’s made him extremely protective of those he loves. He really put his foot down and told Kim the surgery ban is a condition of being with him.”

Even without surgery, Kardashian has been looking great after giving birth to their first daughter, North, in June. On Thursday, she sent fans into a frenzy after she posted a picture of herself in a very revealing swimsuit, showing off her famous derriere.

Kardashian has been working with celebrity trainer Tracy Anderson, who has whipped stars including Gwyneth Paltrow and Nicole Richie into shape.

“She’s a gorgeous woman. I think the reason why the weight is coming off is because she’s very connected. I went and met little North, and Kim’s really taking it in stride,” Anderson recently told E Online. “She’s really connected to the baby, which is what’s important. She’s focused on the baby and nursing and taking her time.”
