Olivia Newton-John, 72, Grease – $40 Million

Olivia Newton-John rose to fame as a singer in the ’70s, but she didn’t stop there. She also gave acting a try and became a massive star after starring in Grease. She always made healthy choices when it came to her lifestyle, and she’s a fan of skin products with natural ingredients.
