Mia Farrow's son Ronan is content to live with the mystery of his paternity after his actress mother revealed Frank Sinatra might be his father in a recent magazine interview.

The Rosemary's Baby star was married to Woody Allen when the 24 year old philanthropist and Tv news personality was born, but she has since confessed that Ronan may have been the product of a final fling with her ex-husband Sinatra, revealing to Vanity Fair that she and the singer remained close after their split.

Ronan, who recently landed his own show on U.S. news network Msnbc, has been asked about his mother's comments, but insists there's nothing he can do to change the past, and as he remains estranged from Allen, there's no way of making sure who his father is - and he is fine with that.

He tells U.S. news show Extra, "I wasn't there so I don't have a lot more to offer... Of course, it is a distraction, but I take it in (my) stride. Look, we all have our families' histories to bear."
