He looks like his grandfather John Farrow. He’s a dead ringer - google it. He also looks exactly like his mother as well.
Barbara Sinatra kept Sinatra under lock and key in his final years. Mia is lying to generate publicity for her silly son.
Anywho...regardless of who he looks like, or whose kid he is...he's a stinkin' lib. That's all I need to know ;)
Ronan was born in 1987... Frank Sinatra died in 1998... Sinatra was doing the Together Again tour with Sammy Davis Jr., and Dean Martin in 1988... his wife could not have been keeping him under lock and key at that time...
You’re right, Ronan looks like the spitting image of his maternal grandfather, John. His mouth, his eyes, even his hair. But shouldn’t we see even a small glimpse of Allen in his features if Ronan is his son?
