If the chemistry is right between actors, sparks fly onscreen — and sometimes offscreen, too. Here are some costars who actually started dating in real life while working together…
1. Kit Harington and Rose Leslie fell in love while playing enemies-to-lovers Jon Snow and Ygritte on Game of Thrones. “If you’re already attracted to someone, and then they play your love interest in the show, it becomes very easy to fall in love,” Kit said.

It translated over from the real-life attraction Katie and Joshua had — they dated in real life during the early seasons. Katie described him as her “first love” and “something so incredible and indescribable.” The pair remained “best friends” after they broke up and recently began working together again (and possibly dating, if the rumors/hopes of thousands of fans are correct).
