Maybe you met them through work, like Shaun White. He met his now-girlfriend Nina Dobrev when they spoke at the same event, but he had no idea she was an actor until they went to dinner afterwards. He was confused when the staff wanted their picture with Elena from The Vampire Diaries, not an Olympic gold medalist!

Or maybe you can relate to Lily Allen, who matched with David Harbour on a dating app. In his picture, he was wearing his police uniform from Stranger Things, so she "thought he was just, like, a sexy policeman from a reality TV show."
