Jenny McCarthy wanted to be a nun when she was younger.

The former Playboy model grew up in a very strict Catholic household and always thought she would join a nunnery and devote her life to God because she wanted to guarantee her place in heaven.

Writing in the Chicago Sun-Times in a promotion piece for her new book, 'Bad Habits: Confessions of a Recovering Catholic', Jenny said: ''I was taught to believe that my goal in life was to do good things so that I could ensure my place in heaven. So, it was only logical in my young innocent mind that I should become a nun - and guarantee my spot to hang out with Jesus and his buddies.''

However, Jenny soon changed her mind when she discovered nuns couldn't have children as she was desperate to become a mother.

The blonde beauty - who has a 10-year-old son Evan, from her former marriage to actor-and-director John Asher - added: ''I knew in my soul that even though I wanted to go to heaven, I yearned to be a mom more than anything in the world.

''Even though I didn't become a nun and have done my fair share of sinning, I've come to realise that you can still fight for justice and truth without having to wear a habit. I just chose to wear a push-up bra instead. Some people might call me a sinner and blame me for my Bad Habits, but I prefer to look at myself like a student in this awesome school called life.''
