Jenna Jameson – Age 47

Born and raised in Los Angeles by her father, Jenna Jameson grew up dreaming of becoming the most famous star in showbiz. In adult entertainment, at least, she managed to do just that, describing herself as “the most downloaded person online.”

By the age of 20, Jameson had already become the poster child for men’s magazines like High Society, Hustler, and Penthouse. She has since translated her popularity into a somewhat successful acting career with films like Zombie Strippers! and Private Parts on her resume. Since 2018, the starlet has been on a mission to lose pounds via a keto diet.
