#18: Brittany and Cynthia Daniel
Brittany Daniel, known for her roles in Joe Dirt, White Chicks, and It’s Always Sunny in Philadelphia, isn’t the only star in the family—she has a twin sister, Cynthia, who also had a taste of Hollywood. The duo first captured attention as Jessica and Elizabeth Wakefield on Sweet Valley High, a perfect casting for real-life twins.

However, while Brittany continued acting, Cynthia stepped away from the spotlight after a final appearance on That ’80s Show in 2002. Trading scripts for snapshots, she found her passion behind the lens, building a successful career as a professional photographer.
