Uma Thurman – 51

Uma Thurman started her career off modeling, but at the age of 16 years old, she became a feature film actress. While the rumor mill is turning, there is no confirmation that Uma has had plastic surgery. As she grows older, she looks more beautiful.

Being an actress can be both physically and emotionally tolling, which was the case with our favorite star too. Often roles required her to take on many different looks. In fact, when Uma starred in K*** Bill, she lost around 25 pounds! The celeb puts this down to Yoga and Pilates and follows a regimented Paleolithic diet of vegetables, grains, and nuts.
