She’s best known for playing Sunny in Flashdance, a role that really put her on the map. After that breakthrough, she went on to find even more success behind the scenes as a television writer and story editor, showing off her talent both in front of and behind the camera. Before all the fame, though, she actually started out alongside her twin sister, Jean—they were famously known as the Doublemint Twins, a fun and memorable part of her early career. She’s one of five siblings total, with Jean being her identical twin, and three other brothers and sisters: Katey, Joe, and David. It’s kind of amazing to think about how far she’s come—from those early days as one of the Doublemint Twins to making a real name for herself in Hollywood.
