Kim Kardashian, who has already had two failed marriages, has opened up about her romance with Kanye West, admitting that she can’t imagine being with anyone apart from the rapper for the rest of her life.Posing in a white bridal-style gown in a stunning new shoot, the 31-year-old reality star explained that West is her “best friend” and their relationship is entirely different from anything she has ever been through before. “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,” the Daily Mail quoted her as telling Tatler magazine.“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,” she added.
