(Cover) - EN Showbiz - Kim Kardashian insists she is proud of her famous butt.

The 30-year-old reality TV star is famed for her curvaceous figure and often highlights her pert derriere in a range of tight attire.

Kim has been dogged by rumours that her butt is in fact the result of a surgical procedure in the past, but the raven-haired beauty is keen to shoot down the reports. She insists her impressive curves are all down to her genes.

"I'm half Armenian, so the butt really comes from my dad's side of the family. It's a little bit bigger so you do have to work out more," she revealed in an interview with the Australian issue of Cosmopolitan magazine. "I do squats and lunges. I try to do whatever I can to work out. It's all real."

Despite previously dabbling with Botox, Kim would never use surgery to change any part of her body. The stunning star, who recently got engaged to her NBA star fianc Kris Humphries, is more than happy with the way she looks. "I'm proud of my booty and it's all mine. I have not had cosmetic surgery" she said. "I tried Botox once, but I have not had my nose done or anything done to my butt. No injections I'm very happy with the way I am." (C) Cover Media
