This is the strangest entry on our love triangle list. Woody Allen and Mia Farrow began dating in 1980, adopting two children together and conceiving one biological son over their 10-year relationship. Allen did not adopt any of Farrow's children from her previous marriages, however, including her adopted daughter Soon-Yi Previn.
Their romance ended when Farrow discovered nude photographs of Soon-Yi in Allen's possession, prompting him to admit he had feelings for Farrow's daughter. Allen has since married Soon-Yi, who is 34 years his junior, and the two have adopted children of their own. - XFINITY Entertainment Staff
