Jenny McCarthy's 'Baby Laughs'

(CBS)  Jenny McCarthy first made a name as an actress. She later became a best selling author with her book about pregnancy. Now she tells The Early Show co-anchor Rene Syler she is excited to get to make her fans laugh with her second book, "Baby Laughs: The Naked Truth About the First Year of Mommyhood."

"I realized that nobody tells it like it is as much as me," she says. "I kind of do it so that you can learn and be entertained at the same time. I think it makes girls comfortable to know that a celebrity has stretch marks and cottage cheese all over her butt also."

McCarthy points out as well that once you have a baby most people would say your life will be over, but that is not so.

"It is the most wonderful thing that's ever happened to me," she says. What she found surprising was how her body was going through major changes.

She says, "I didn't know that my hormones really wouldn't go away for another nine months, that I was still not in the mood, so to speak, for nine months. The fat wouldn't come off. That was one of the biggest things. I was terrified I was never going to get my body back."

A hilarious part of the book is how she describes the first time she looked in the mirror after delivering her baby.
