In the early to mid '90s, prolific writer/director Woody Allen was at the center of one of the most bizarre scandals to ever rock the film world. Woody had been married to actress Mia Farrow for 12 years, but their relationship ended in 1992 after Mia discovered nude photos Woody had taken of Soon-Yi Previn, the daughter Mia had adopted with her ex-husband, Andre Previn. Soon after, Woody split from Mia and began a relationship with Soon-Yi, who at the time was 22 years old. And contrary to popular belief, Woody was never Soon-Yi's stepfather. Not like that makes the situation any more normal, but still.
Over 20 years later, this relationship is still going strong. In fact, the two have a child together.
