Mia Farrow was never positive that Woody Allen was her son, Ronan Farrow's father. Now, she's admitting that it's possible that the 25-year-old was fathered by Frank Sinatra.

According to CBS News, Farrow was married to Sinatra for 18 months. After they were divorced and Farrow began a relationship with Allen, Farrow and Sinatra and Farrow continued to see Sinatra on the side, so it's likely that Ronan, with Sinatra's blue eyes, is a love child for the pair. If Sinatra was the father, he would have been 78 years old when Ronan was conceived.

Ronan took to Twitter Wednesday to reveal his feelings on the matter, saying “Listen, we're all *possibly* Frank Sinatra's son.”

As for Allen, a representative for the actor/director told the Associated Press, "The article is so fictitious and extravagantly absurd that he is not going to comment."

A DNA test to determine paternity has never been conducted.

An interview with Farrow will be featured in Vanity Fair's November issue.
