The reason why Woody Allen and his wife of 16 years, Soon-Yi Previn, earned a spot on this list should be self-explanatory, but in case you're not privy, we'll just start with the story of how they met: Allen was in a serious relationship with actress Mia Farrow at the time, and Soon-Yi was Farrow's adopted daughter from a previous marriage.
