(Cover) - EN Showbiz - Kendra Wilkinson believes Hugh Hefner has not decided to marry until now because he was too young before.

The glamour model used to date Playboy founder Hugh and has become a star in her own right, fronting her own reality show.

He recently announced that he is to wed model-and-singer Crystal Harris after dating numerous pretty younger women.

And Kendra thinks that Hugh, despite the fact he is now 84, thought he was too youthful to enter into a union before.

Hes like any man - he was having fun and wasnt ready. I guess he was too young! Kendra joked to In Touch.

The gorgeous 25-year-old once starred alongside another of Hughs former girlfriends, the model Holly Madison, in The Girls Next Door.

And Kendra admits she is shocked that the magazine magnate didnt take his relationship further with the voluptuous blonde.

We all thought it was going to be Holly! she explained, referring to what her and her colleagues thought would happen at the time. (C) Cover Media
