Can't imagine life without Kanye West: Kardashian (AP)

She has been dating the rapper for six months.

"It's so nice to have a best friend in this game who understands everything you're going through. Being with someone I've known for so many years is comforting," showbizspy quoted Kardashian as saying.

"He's been there through so many different stages of my life and before I was famous, so this relationship is a different thing entirely. It's good to be aware that he definitely doesn't want anything from me too, because he understands the business.

"I can't even think about being with anyone else than the man I'm with," added the 31-year-old.

Kardashian split from her husband Kris Humphries October last year following a brief marriage. They are yet to get officially divorced.
