Reality star Kim Kardashian is so sick of people questioning whether her behind is real or not, that she went and got an X-ray to prove that it is all natural and not enhanced. UsMagazine.com is reporting that Kim went to her family doctor to help her prove that her ass was real and not her enhanced with implants.

In an upcoming episode of the reality show 'Keeping Up With the Kardashians,' Kim goes to her family doctor and tells him, "My sisters have dared me to get a butt X-ray. I really just want to get [it] so I can show the whole world."

Her sister Khloe suggests a more hands on approach by the doctor, "You could just feel her ass up and see if it's real. You're a doctor -- you'll know."

Khloe later on went to say, "The fact that Kim is actually laying on a table and actually getting an X-ray of her ass is, like, [her butt is] iconic. Are you serious?!"

Khloe later tweeted the image of Kim and her x-ray saying, "Kim got a butt X-Ray... See, it's REAL!!! LOL"
