Love and Betrayal: A-List Actors Accused of Cheating with Their Co-Stars
Harrison Ford and Carrie Fisher
Han Solo and Princess Leia have one of the most celebrated fictional romances ever. However, their Star Wars actors also had a brief tryst. Fisher was only 19 when she began the secret relationship with her co-star. Ford was 13 years older than her and surprised her because she was very insecure.

Vanity Fair
Fisher wrote in her biography: “We all became famous at that time, but there were other things to focus on, and certainly the affair was a formidable distraction. And maybe that made the fame less confusing because it didn’t have all of my focus (via The Guardian).”
