Mary-Kate and Ashley Olsen were child stars who became famous for their roles on the TV show Full House and went on to star in movies and create their own brand, Dualstar. However, after nearly two decades in the spotlight, the twins effectively disappeared from public view. They retired from acting in 2012 and have since focused on their careers in the fashion industry. They have also maintained a no-social-media status for years and rarely appear at public events. Mary-Kate checked herself into rehab for an eating disorder and an alleged drug addiction in 2004. Mary-Kate Olsen also experienced a rough divorce from Olivier Sarkozy in 2021. Despite growing up under a microscope, the twins have always had an excellent sense for business, and both are almost retired at this point.
