Kaley Cuoco – 33

Actress Kaley Cuoco is best known for being one of the main stars of the recently-concluded sitcom, The Big Bang Theory. Cuoco has always been a blonde but there was a time when she went for a silver look. The hair color she had made her look very hip and trendy. However, she had to revert to her blonde mane for her character on The Big Bang Theory. Meanwhile, fans of the Big Bang should now cut her a little slack as she has the freedom to get whatever color she wants after the show. Cuoco is set to produce and star in a new movie called The Flight Attendant.
