– Woody Allen and Mia Farrow's brainiac son has ripped his famous dad as "my brother-in-law" because of the aging director's marriage to one of Farrow's adopted daughters. The zinger came on Father's Day. "Happy father’s day—or as they call it in my family, happy brother-in-law’s day," tweeted Ronan Farrow. Mom followed it up with a one-word retweet: "BOOM." Allen and Mia Farrow had an infamous falling out after a years-long affair when Farrow discovered nude photos of her daughter Soon-Yi that had been taken by Allen. Ronan, 24, has been estranged from his pop for decades. “He’s my father married to my sister. That makes me his son and his brother-in-law," Ronan has griped in the past. "That is such a moral transgression.” Ronan, a Rhodes scholar, entered college at the age of 11 and was accepted into Yale Law School at 15. He's deferring enrollment while he serves as special adviser to the Secretary of State for Global Youth Issues and director of the State Department’s Global Youth Issues office. He was five when his parents broke up over his pop's affair with his sister. Allen, now 76, and Soon-Yi, now 41, have adopted two daughters. Click for more.
