Valerie Bertinelli — Age 61

There’s no doubt that the American actress Valerie Bertinelli knows how to keep her youthful looks going. But this former Golden Globe Award winner also knows how to reinvent herself. Over the years, she went from being a sitcom superstar to becoming a celebrity cook and Food Network icon.

While older viewers may remember Bertinelli from her appearances on “One Day at a Time,” younger audiences will recognize her from her work in shows such as “Valerie’s Home Cooking” and “Kids Baking Championship.” In 2021, she was featured in the TV series documentary “History of the Sitcom.”
