Now: Jenna Jameson
Jenna Jameson has since transitioned into more mainstream projects like the 1997 Howard Stern film, Private Parts. However, she remained active in her original industry during that time. After all, she founded her very own adult movie company with her ex-husband Jay Grdina. In 2004, Jameson published an autobiography called How to Make Love Like a Porn Star: A Cautionary Tale. Isn’t it impressive that the book made it all the way to the prestigious New York Times Best Seller List? In 2008, she quit born and started focusing on her modeling career instead.
