Mia Farrow's son Ronan may be the offspring of Frank Sinatra and not Woody Allen, Farrow told Vanity Fair.

Ronan, 25, was thought to be Farrow and Allen's only biological child.

Vanity Fair released part of the interview for their November issue, teasing that Farrow admitted to Sinatra being the great love of her life. When asked point blank if Ronan Farrow was actually the son of Frank Sinatra, Farrow answered, "Possibly."

After the news broke, Ronan Farrow tweeted, "Listen, we're all possibly Frank Sinatra's son."

No word yet from Woody Allen's camp, but maybe he should have seen this coming. After all, Allen did run off with Farrow's adopted daughter Soon-Yi Previn.

Reportedly, no DNA tests have been done. When Vanity Fair asked Sinatra's daughter Nancy about Ronan being treated as if he were a member of her family, she answered in an e-mail: "He is a big part of us, and we are blessed to have him in our lives."

Whoa. Imagine going from believing Woody Allen is your father to hearing you're spawned from the Chairman of the Board. That's like hitting the genetic, bad-ass lottery.

According to the New York Post's Page Six, rumors about Ronan being Sinatra's son have circulated for years, though this is the first time Farrow acknowledges the possibility. Farrow and Sinatra were only married from 1966 to 1968, but continued a relationship afterward, even after Farrow was with Allen. Sinatra, who died in 1998, would have been 78 at the time of Ronan's conception.

Wow -- 78. The old rascal still had it.

The Washington Post reported there's a physical resemblance between Sinatra and Ronan, a human rights lawyer who frequently accompanies his activist mother around the world in her endeavors as a UNICEF ambassador.
