Jerry Lee Lewis
Not only did Jerry Lee Lewis as a 23-year-old marry Myra Gale Brown a 13-year-old, but she was also related to him. Their marriage caused great controversy in rock n’ roll history and rightfully so. Lewis went from making thousands of dollars per performance to making less than $300. Their marriage survived more than a decade but completely ruined Lewis’s career. To make it worse, in 1970, Myra filed for divorce and accused Lewis of abuse and adultery (via NY Post).
