"Possibly" Mia Farrow's son by Woody Allen is actually the biological offspring of Frank Sinatra.

That's the late-breaking scoop in Vanity Fair.

Scroll down for a photo of the son, now called Ronan Farrow. He looks a lot like Mia, but does he look at all like either Frank Sinatra or Woody Allen? He's got blue eyes...

No DNA tests have been done. When Orth asks Nancy Sinatra Jr. about Ronan’s being treated as if he were a member of her family, Sinatra answers in an e-mail, “He is a big part of us, and we are blessed to have him in our lives.”

Why have no DNA tests been done? It's easier, in this case, to think of reasons why there would be denial of DNA tests that were done. Considering the severity of Ronan and Mia's rejection of Woody Allen, you'd think they'd love to be able to say, as a scientific fact, that Ronan is not Woody's son. And what delight in being about to claim Frank Sinatra as one's father!

I smell hooey.

UPDATE: "Listen, we’re all *possibly* Frank Sinatra’s son." And: "It’s an unusual thing to do with one’s mother..."

ADDED: I indulge in much more analysis here.
