Kim Kardashian commissions 'artistic' bum sculpture

Kim Kardashian has reportedly commissioned an ''artistic'' bum sculpture as a gift for her husband Kanye West.

The 34-year-old reality star - who shocked the world after she posed nude in a photoshoot for Paper magazine last week - has reportedly paid £13,000 for a Silicon replica of her behind as a gift for her 37-year-old rapper husband.

A source told The Sun newspaper: ''The replica was her idea for a gift, she thinks it's artistic and knew Kanye would love it. ''It means he'll always have a piece of her, albeit her bum, if Kim's away working.''

Kim is currently in Australia with her 17-month-old daughter North West to promote her new fragrance Fleur Fatale, but she still took the time to defend her controversial decision to get naked for the publication on the Australian talk show 'The Project'.

She said: ''As a role model I'm not saying anyone else should do that, but for me it was an art project and it taught me to do what you want to do. ''I'm never one to preach, but I felt really positive and really good about myself. I love the photos, I did it for me. I hope other people like them.''
