Barbi Benton — Age 73

Not everyone gets to pose for the notorious men’s magazine. One has to be immensely beautiful and foxy to get the opportunity, and of course, Barbi Benton did during the ’70s. In fact, she was romantically involved with the founder of the said magazine around that time.

Today, Benton is on the verge of turning 71 although, you’d never peg her for an older woman. She still looks glorious, and not a day goes by where we don’t wonder about the secrets behind the youthful looks. Despite being one of the steamiest women of the time, Benton retired in 1986 to become a full-time mother to her kids with George Gradow.
