Susan Colleen Duff – 69 years old (2023) | Hilary Duff – 35 years old (2023)

Sometimes, all a star needs is a good foundation. This is the case for Hillary Duff, whose parents, Robert Erhard and Susan Colleen Duff, provided just that. While Robert was a partner in a chain of convenience stores, her mother was a homemaker who ensured everything was in place for her and her sister Haylie.

This allowed Hillary to focus on things like school, and acting, and being Lizzie Maguire, which gave her initial fame in the eponymous show. Duff also moved into music, and her mother has followed her course, moving into film and music production. In 2021 Hillary starred in the final season of the series “Younger.”
