Kim Kardashian takes x-ray of rear end to prove it’s real

You can now sleep soundly: Kim Kardashian’s giant backside is all natural.

The “Keeping Up with the Kardashians” reality television star, who has battled rumors that she underwent butt enhancement surgery, went in for an x-ray to prove she has never had plastic surgery to enhance her derrière. (Bill O’Reilly: Kim Kardashian a ‘pinhead’)

Last week, Khloe Kardashian posted a picture on her blog of sister Kim’s x-ray, which appears to show an outline of Kim’s untouched behind.

“Hey dolls. The PROOF is in the X-ray. Kim’s [butt] is 100% real!!!” Khloe wrote.

Kim herself retweeted a link to her sibling’s post and wrote, “Haha! The things my sisters have me do! Proof baby!”

The whole ordeal was documented in a recent episode of “Keeping Up with the Kardashians” that showed Kim visiting a medical professional for advice on how to prove that her assets were God-given.

“My sisters have dared me to get a butt x-ray,” Kim said to the doctor. “I really just want to get [it] so I can show the whole world.”

The doctor took an x-ray of Kourtney Kardashian’s breast implants to compare the results to Kim’s booty x-ray shots.
