Well, this is definitely one way to sell a book: Carrie Fisher, best known for her role as Princess Leia in the Star Wars franchise, revealed that her upcoming book, The Princess Diarist, talks about her long-ago affair with co-star Harrison Ford.

The actress told People that at 19 while filming Star Wars back in 1976, she had a 3-month romance with her then-33-year-old co-star Ford, who played Han Solo in the film. At that time, Ford was married to his first wife Mary Marquardt, and had two children (the couple divorced in 1979).
