Hugh Hefner and his girlfriend Crystal Harris' relationship is now exclusive.

The Playboy founder - famed for having a harem of girlfriends living with him in his Playboy Mansion - says he has found "true love" at 84 and is planning a future with Crystal.

Hugh, who celebrated his birthday in Las Vegas last weekend, said: "She's very real, and although she has her aspirations, the major thing in her life is our relationship. The problem with some of the other girls is that there were other motivations, their careers. This is more like true love. She is, as they say, 'the real deal.' "

The magazine magnate asked his other girlfriends to move out of the Playboy Mansion and into the neighbouring Playmate House at the beginning of this year, and has previously hinted he is considering marrying Crystal.

He has also vowed to never cheat on her, despite being surrounded by beautiful women on a daily basis.

He added: "When you get married, you make a commitment. I had a lot of girlfriends, but it's not the same as cheating. I don't cheat. I am very open about what I do."

He also had stern words for motorcycle entrepreneur Jesse James, who has been accused of cheating on his wife Sandra Bullock with a string of other women.

Hugh added: "Sandra Bullock's husband looks like a real creep. I think that when you are in a relationship, you should be honest. The real immorality of infidelity is the lying."

On the subject of marriage, twice-wed Hugh has previously said: "It's certainly possible. I certainly love her enough. We'll see. I'm having more fun than I did when I was 20.

"I haven't had a lot of luck with marriage. I don't have a good track record and I don't want to screw this one up."
