Kim Kardashian has revealed that herself and hubby Kanye West have an "amazing sex life" during an interview with GQ magazine.

The 33-year old - who has posed naked for the men's publication - made the confession when addressing THAT sex tape with ex-boyfriend Ray J, which leaked in 2007.

“My husband Kanye and I have an amazing sex life,” she said. “So far as the sex tape is concerned, whether or not we’ve made another … If we have, it’s never something I want to go public.”

Kimmy added: “I never want to make the same mistake twice."

The socialite also admitted that showbiz pal Pharrell Williams helped her and Yeezy decide to call their daughter North, with Kardashian explaining: "It was a rumour in the press and we’d never really considered it seriously.

She continued: “Then a little while later Anna Wintour came over and asked the same thing. She told us: ‘North is a genius name.’

“Kanye and I looked at one another and just laughed. I guess at that point it sort of stuck."
