84-year-old Hugh proposed to Crystal Harris, 24, on Christmas Eve and Hugh`s former girlfriend and one-time Playboy Playmate Kendra Wilkinson thinks the timing couldn`t be better because Hugh is only now mature enough to handle marriage.

Kendra - who admitted she was surprised Hugh never married former girlfriend Holly Madison - told In Touch magazine: "We all thought it was going to be Holly! He`s like any man - he was having fun and wasn`t ready. I guess he was too young!"

Holly has previously revealed her dismay at the engagement, saying she is worried Crystal is using Hugh - who has been married twice before - to start her career and fears he could end up losing everything in an expensive divorce.

She said: "I`ve seen a lot of girls try to date Hef, and some have ulterior motives. I don`t think it would be a bad idea for him to get to know her a little better. "I think it`s possible Crystal could break Hef`s heart. They could end up divorcing, and she could take half his money.

"I`m not jealous that he`d marry someone else. I just don`t want it to be a girl who`s using him to start her career. Basically, I think he could do better than Crystal."
