Jenna Jameson's the adult film queen who made it into Forbes magazine by turning her bare essentials into a million dollar production company. Now the sex icon is adding another notch to her risque resume, as the author of the no-holds-barred book, "How to Make Love Like a Porn Star: A Cautionary Tale."

"I thought I should probably put it in print before I forgot everything," Jenna told us of her steamy tell-all, in which she unearths dozens of never-before-seen photos and goes under the covers to reveal her own private sexploits.

"I never thought I was going to become famous for having sex," she laughed. "It just happened to be a talent of mine."

Jenna also reveals the celebs she claims she's dated, like Tommy Lee and Marilyn Manson, who she told us is, " A very, very intelligent man."

Jenna says that, despite its title, her book's not really a "how-to," but does give advice on spicing up your sex life. "It's very important that women lose their inhibitions," she insisted. "And the men, they certainly need to slow down."

And you can read more about Jenna's life in the fast lane for yourself, her book is in stores now.
