6) Diane Keaton

A long-time advocate of natural aging, Keaton has always denied undergoing cosmetic surgery. The actress has even joked in interviews that her secret is wearing gloves to hide aging hands. Critics say that her skin is exceptionally smooth and her jawline is too sharp, which might imply Botox or even a facelift. Keaton, who always dresses in quirky fashion and never apologizes for it, credits genetics and self-confidence for her good looks. Whether natural or assisted, her ageless looks keep the guesswork going on.
