#2 Soon-Yi Previn and Woody Allen
Let’s just ignore the 35-year age difference between Soon-Yi Previn and Woody Allen, and focus on the couple’s unbelievable “love” story. Woody Allen was dating Mia Farrow when he met Soon-Yi, as Soon-Yi was Mia’s adopted daughter from an earlier marriage. So that makes her Woody’s step daughter. The two met when she was really, really young. And that’s not even the worst part. Woody Allen (age 78) has been married with Soon-Yi for 15 years.
