Barbara Sinatra: Mia Farrow's son isn't Frank's

• Mia Farrow told Vanity Fair her son Ronan could be Sinatra%27s
• Barbara Sinatra says her husband left nothing to Ronan
• Woody Allen%27s rep says he has no comment

PALM SPRINGS, Calif. -- Rumors that Mia Farrow's son was fathered by the late Frank Sinatra is "a phony deal," Sinatra's widow, Barbara Sinatra, said Wednesday.

Farrow, who was married to Sinatra for 18 months from July 1966, revealed to Vanity Fair in the magazine's November issue that the son she had while married to Woody Allen was "possibly" Sinatra's.

The son, Ronan Farrow, is 25, so Sinatra would have been 73 at the time of his birth. A DNA test has not been performed.

Sinatra married Barbara Sinatra in 1976 and the couple lived primarily in Rancho Mirage, Calif., in the late 1980s. But Mia Farrow told Vanity Fair she and Sinatra "never really split up."

Ronan Farrow tweeted Wednesday, "Listen, we're all possibly Frank Sinatra's son."

A representative for Allen told The Associated Press, "The article is so fictitious and extravagantly absurd that he is not going to comment."

Barbara Sinatra, who still maintains a house in Rancho Mirage, hadn't heard of the reports when reached by telephone by The Desert Sun. But then she said, "I can't hardly believe that. It's just a bunch of junk. There's always junk written — lies that aren't true."

Frank Sinatra's probate case was heavily covered by the media after his death in Beverly Hills in 1998.

Barbara Sinatra said there was nothing left to Ronan Farrow from her husband's estate.

The singer's daughter, Nancy Sinatra, who also has a home in Rancho Mirage, told Vanity Fair that Ronan Farrow "is a big part of us, and we are blessed to have him in our lives."

But Barbara said, "It sounds like a phony to me."
