Justin Timberlake & Ryan Gosling
Everyone knows that Justin Timberlake and Britney Spears first met on The Mickey Mouse Club, but they weren’t the only two future stars on that cast. Timberlake was friends with Ryan Gosling on the show, and they even lived together.
Gosling lived their family for a few months during shooting, and they were somewhat notorious as pranksters. As Justin would later reveal in interviews, they did things like steal golf carts and other shenanigans. The two of them are still friends to this day, and have been extremely successful in their respective fields.
