Back in 2013, Mia Farrow told Vanity Fair that Ronan Farrow -- her son long-believed to be fathered by her ex, Woody Allen -- was "possibly" the son of Frank Sinatra. Although Farrow and Sinatra divorced in 1968, she admitted they maintained a relationship long after that (Ronan was born in 1987).
Now, Sinatra's undisputed biological children are weighing in on the subject. When asked about Ronan possibly being Frank's son on CBS Sunday Morning, Nancy Sinatra responded, "Mia's son? Oh, nonsense." Nancy said Frank would have "laughed it off" if he were still alive. "I was kind of cranky at Mia for even saying 'possibly' because she knew better."
