Disgraced socialite Kim Kardashian denies she underwent surgery to improve her bottom, insisting it is her ethnicity that gives her curves.

The pretty brunette - who hit the headlines last year when footage of a sex romp with rapper Ray J was leaked to an internet porn firm - claims she is not against cosmetic surgery, but does not think it is necessary given her natural curves.

She says "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."
