Woody Allen and Soon-Yi Previn
The romance between director Woody Allen and Soon-Yi Previn was quite the scandal, and it remains a bit controversial today even though they've been married since 1997. They began dating in 1991, when Woody was still dating actress Mia Farrow, Sun Yi's adoptive mother – and the mother of three of his children. Somehow they've managed to buck the odds with a nearly 20-year marriage, despite their 35 year age difference. He's 79, she's 44.
