Ronan Farrow is the biological son of Woody Allen and Mia Farrow. Allen, of course, is now married to Rowan’s adopted sister, Soon-Yi Previn.

We’re guessing Ronan shies away from the V.C. Andrews novels. His therapy bills have gotta be huge.

Ronan reportedly once said:

He’s my father married to my sister. That makes me his son and his brother-in-law. That is such a moral transgression. I cannot see him. I cannot have a relationship with my father and be morally consistent. I lived with all these adopted children, so they are my family. To say Soon-Yi was not my sister is an insult to all adopted children.

Happy Brother-in-Law’s Day? Even Politifact would have to rate that one “true.”

Mia Farrow appreciated the tweet.
