Although marriages between first cousins were more common—and socially accepted—last century, that didn’t stop Jerry Lee Lewis from wedding his cousin Myra in the ’50s when she was only 13 years old. The rock ‘n’ roll star tried to keep the marriage, which came during the height of his fame, hidden from the public, but after a British journalist learned about the 23-year-old’s relationship (and third marriage), his fans were outraged. With the piano man’s reputation ruined, his British tour was canceled, and it took decades for his career to recover, though it never reached its previous heights. The Lewis’ relationship came to the screen when Dennis Quaid played the star in the 1989 film
Great Balls of Fire!, based on the book by Myra, who was played by Winona Ryder.
