NANCY SINATRA: FRANK & MIA PATERNITY RUMORS SOMETHING “STUPID”

Nancy Sinatra Ronan Farrow Not Frank Sinatra Son

Old Blue Eyes’ boot walkin’ daughter NANCY SINATRA hits chat show- denounces MIA FARROW paternity claims about son Ronan. VIDEO

Nancy, 74, dismissed the rumors as “nonsense”.

She made the comments that were postred online today to promote new HBO doc Sinatra: All Or Nothing at All airing Sunday on HBO.

Mia Farrow had suggested that her ex-hubby Frank Sinatra might have “possibly” been the father of her son Ronan, sparking a flurry of interest.

“Mia's son? Oh, nonsense," Nancy Jr. told CBS Sunday Morning.

"He would just laugh it off. We didn't laugh it off because it was affecting my kids, you know. They were being questioned about it and we all knew it was nonsense."

"I was kind of cranky with Mia for even saying, 'Possibly,' she added.

 "I was cranky with her for saying that because she knew better, you know, she really did. But she was making a joke! And it was taken very serious and was just silly, stupid."

Frank and Mia were married for two years in the 1960s but she was in a relationship with Woody Allen when she bore the blue-eyed look-a-like before their headline making split in 1992.

POP FYI: Nancy is the daughter of Frank and his first wife Tina Barbado and struck gold with her chart busting “These Boots Are Made For Walkin” single which was written by Lee Hazelwood.
