Jenny McCarthy's 'Baby Laughs'

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. She says, "I can show you this jelly roll around the stomach, along with the hairy legs. Who is going to shave? Because who is really looking? Really. And the stretch marks all over. I mean, this is what I wanted people to see, that I went through it, too! And crying in the mirror. And then I realized, I haven't even turned around to look at my butt yet. That's a whole other book!"

Besides losing weight, McCarthy lost some of her girlfriends, something she describes in her book.

"It's all about how your single friends think you are now the most boring thing in the world," she says, "They couldn't care less about your kid's baby poo or those stories or the first milestone. They're thinking about what guy they want to hook up with tonight and you become the most boring person in the world to them. You start to gravitate towards women with a really cute diaper bag and those are the people who are your new friends."

Now that her baby is 3, she says she is trying to get pregnant again.
