Christina Applegate

Because her mother is an experienced actress, it comes as no surprise that Christina Applegate eventually followed suit. In fact, when she was just a year old, Applegate landed a part alongside her mother in the soap opera Days of Our Lives. Plus, at just three months old, she even appeared in a commercial for Playtex baby bottles. Without knowing, her foot was on the metaphorical gas pedal, headed toward an acting career before she even learned how to walk.

At nine years old, Applegate landed her film debut, performing in King Cobra. It was during her teen years, though, that she landed her big break, which was the role of Kelly Bundy in Married… with Children. Since then, the now-more experienced actress has been able to maintain a successful career under the spotlight, starring in projects like Dead to Me, Anchorman: The Legend of Ron Burgundy, The Big Hit, and Up All Night.
