Woody Allen and Mia Farrow
After a 12 year relationship, Woody Allen and Mia Farrow were involved in the nastiest custody battle in 1992. Farrow filed for divorce after discovering that Allen had taken one too many nude photos of her daughter Soon-Yi. Allen, then 56, had been having a sexual relationship with 21-year-old Soon-Yi. Farrow ultimately won custody of their three children together.
After over two decades, Allen and Soon-Yi are still together. The couple married in 1997 in Venice, Italy. They also adopted two children, Bechet 13, and 12-year-old Manzie, whom the couple named after jazz musicians in honor of their shared love for jazz music.
