Marion Ross – 89

Marion Ross got her first taste of how being a celebrity feels like when she appeared in the famous sitcom Happy Days from 1974 until 1984. During the ’90s, her acting career became even bigger, as apart from voice acting in popular animated series like SpongeBob SquarePants, she landed notable recurring roles in hit shows of the time, such as That ’70s Show and Gilmore Girls. Her online savings account now holds $10 million after decades of quality acting, and though she’s almost 90 years old, she looks just as glamorous as she used to be during her heyday.
