In December 1987, Mia Farrow and Woody Allen welcomed their only biological child, Ronan Farrow. However, Ronan’s appearance has been a subject of discussion since he was born.

Ronan grew up to boast

deep blue eyes and striking angular features, making his appearance a lot less like Allen and a lot more like another famous entertainer.

Between 1966 and 1968, Mia Farrow was married to Frank Sinatra — the duo remained close until Sinatra’s death — and many believed that Sinatra was Ronan’s biological father.

“He came back, over and over and over [...] I mean, we never really split up,” Mia told Vanity Fair in 2013. Could Ronan be Sinatra's, then? “Possibly,” she told the interviewer.

Ronan is well aware of the speculations surrounding his parentage. “Listen, we're all *possibly* Frank Sinatra's son,” he had tweeted after his mother's interview.
