Victoria Principal – 71
According to a Daily Mail article, Victoria Principal has consistently denied going under the knife, although she used to be married to a plastic surgeon. Since the two-time Golden Globe nominee began her entertainment career during the ’70s, some of her features have, of course, changed with age.

Principal became famous for playing the role of Pamela Barnes Ewing on “ Dallas,” the American primetime TV soap opera. She was on the long-running show for nearly a decade, leaving in 1987. Since then, she has created her own line of skincare products called Principal Secret.
