The road from God-fearing Catholic schoolgirl to Playmate of the Year is always a complicated one, but it can also be quite funny. Jenny McCarthy has already written six best-selling books, but she’s never delved so deeply into her ultra-religious upbringing as she does in Bad Habits: Confessions of a Recovering Catholic (Oct. 2). Growing up, the former Playboy mainstay dreamed of becoming a nun rather than an actress/model, and the book chronicles the many twists along the way that took her life in a very different direction.

Check out the irreverent trailer for Bad Habits, which follows McCarthy as she attends a reading group for nuns. It looks to me like a preview for an actual reality show on Lifetime.
