Kim Kardashian has had a butt x-ray to "show the whole world" she has not had implants.
The reality TV star—due to marry basketball player Kris Humphries later this summer—laid to rest speculation that her behind has been surgically enhanced after being dared by her sisters Kourtney and Khloe.
In the latest episode of Keeping Up With the Kardashians, she tells a doctor: "My sisters have dared me to get a butt X-ray, because there are so many people claiming I have butt implants and I'm so tired of them.
"I really just want to get it so I can show the whole world."
Khloe suggests to the medic, rather than going to the trouble of an x-ray, "you could just feel her ass up and see if it's real. You're a doctor—you'll know."
As a comparison to Kim's butt, the doctor also x-rays Kourtney's breast implants, to show the difference on the printouts.
Kim has previously said she is proud of her curvaceous figure, but complained she finds it hard to get rid of cellulite.
She said: "I think it's important to find the one part of your body that you love and accentuate it. For example, because I have a small waist, a big butt and thin legs, belts work for me.
"Although, when I'm in Los Angeles, I exercise every day. And I'll say it. I think my thighs are jiggly and I have cellulite."
