The movie and former "Friends" actress -- recently named by Men's Health Magazine -- is just one of the big and small screen stars in Hollywood's career-defying set. Who else makes THR Fash Track's list?

Jennifer Aniston was named the "Sexiest Woman of All Time" by Men's Health magazine, which ran photos of the the actress and 99 other sexy ladies on its website. The title is high praise and very well deserved.

But what really makes this honor culturally interesting is that Aniston is over 40, otherwise known as way past the expiration date on the shelf life of female sexual appeal, especially in age-conscious Hollywood. Such sexiest woman titles are usually reserved for young nubile 20ish actresses.

But Aniston is just one of many Hollywood beauties who are redefining what it means to be in your 40s and will no doubt redefine the 50s, 60s and 70s as well.

Credit their youthful appearances to healthy eating, regular fitness and tough workouts, (hey-low, personal trainers?) vitamins, good genes (which is always so annoying) as well as advances in dermatology (freezers, fillers and lasers)  and even some subtle plastic surgery. As Jane Fonda, who looks incredible at 73 after some scalpel sessions, admits, "Money helps."
