Ronan Farrow's Father: Frank Sinatra or Woody Allen? Mother Mia Farrow Reveals Famous Singer Might Actually be Her Son's Dad (PHOTOS, TWEETS)

Mia Farrow said on Wednesday that Woody Allen may not be the father of her son Ronan - his dad might actually have been Frank Sinatra.

For years, the public has questioned whether her 25-year-old son was actually fathered by the funnyman actor and director. For the first time, Farrow has acknowledged that the legendary singer was "possibly" Ronan's true parent.

Her son tweeted on Wednesday in reference to the news, joking, "Listen, we're all *possibly* Frank Sinatra's son."

The claims come just days after Farrow's adopted daughter Dylan talked to Vanity Fair about the "crippling" fears she felt over the alleged abuse that Woody Allen reportedly subjected her to.

"I'm scared of him, his image," she told the magazine, adding that she won't even speak her adopted father's name. Allen, 77, has maintained that his former partner Mia Farrow fabricated that he sexually abused Dylan.

In the interview, 68-year-old Mia Farrow referred to Sinatra as the biggest love of her life, adding that "We never really split up." The two married in 1966 when she was 20 years old and he was 50 - they broke up 18 months later, after Farrow did not want to let go of her role in Rosemary's Baby to star in a film with her husband instead. They divorced two years later.

Farrow began having relations with Woody Allen in 1980, but they never lived together. They ended things in 1992 when Farrow found out that Woody Allen was having an affair with his adopted daughter Soon-Yi Previn. Farrow found naked photos of Soon-Yi that Allen had, throwing the pair into a wild custody battle over their children.

Ronan and Allen reportedly never got along, and Farrow's son has never parsed words when it came to his relationship with the comic.

"He's my father and married to my sister," the Daily Mail reported Ronan as saying. "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."

Does Ronan Farrow bear any resemblance to Frank Sinatra? Or is he a dead-ringer for Woody Allen?
