Kim KardashianKim Kardashian has laughed off rumours that her rather round derriere is the result of cosmetic surgery.

Kim, who made her name on the socialite circuit with friend Paris Hilton, told King magazine recently that it’s all down to her ethnic background: “Everyone now says I have a fake butt or butt implant.”

“I’m Armenian; you should see all the women in my family. The women have bigger breasts and bigger butts. That’s how I was born. I can’t help it. I’m not gonna fight it.

“I definitely need to work out more and tone up, but I’m proud of my body.”
