The 85-year-old widow described the revelation as "a phony deal and called the claim, that the 'My Way' singer was "possibly" the father of Ronan, a "bunch of junk", the Mirror reported.
During a recent interview with Vanity Fair, the 68-year old actress made the claim adding that Sinatra was her life's great love, and they never really split up.
Rumors about the identity of Ronan's father have dogged the actress for years with many pointing to similarities in looks between the two men.
Farrow was married to the 'One For My Baby' hitmaker in 1966 before they split in 1968, while her son was born on December 19, 1987.
