Kendra Wilkinson entered the Playboy Mansion because it offered her an escape route.

The blonde beauty is currently appearing in 'I'm a Celebrity ... Get Me Out of Here!' and has been reflecting on her relationship with Hugh Hefner, the 88 year-old Playboy magazine publisher.

Kendra, 29, shared: ''He asked me to be one of his girlfriends and I was like I don't know what that means but hell yeah I'm there.

''I was living in the smallest apartment with the ugliest **** and I was praying for anything to get me out of there.

''He asked me to be part of the Playboy Mansion and I accepted, of course. I went by straight away but I didn't know that sex was involved.

''He'd ask if you wanted to go upstairs, and that was that. I was 18 and he was 78.''

Asked if she was obligated to have sex with the ladies' man, Kendra added: ''I was just curious about the girlfriends because he's always got more than one and wondered if you have to do him?

''You're not obligated, it's your choice.

''He really looks at the women in his house as relationships. Honestly? They all sleep with him - but they're also the greatest people.''
