Mia Farrow's son with Woody Allen, Ronan, may be Frank Sinatra's child, she tells Vanity Fair.
When asked whether Ronan is Sinatra's son, Farrow tells the magazine, "Possibly."
No DNA tests have been done but Ronan was treated like a member of the Sinatra family, according to Nancy Sinatra Jr.
"He is a big part of us, and we are blessed to have him in our lives," she tells the magazine in an e-mail.
Farrow tells Vanity Fair that Sinatra was the great love of her life and says, "We never really split up."
The magazine also talks to Farrow and Allen's adopted daughter Dylan, whom Allen allegedly sexually abused.
In her first on-the-record comments about the incident, Dylan, who now has another name, says of Allen, "I'm scared of him, his image."
"I was doing it because I was scared. I wanted it to stop," Dylan says of the alleged abuse.
Allen still denies the allegations, his lawyer tells Vanity Fair.
Meanwhile, others in Farrow's life have tried to eliminate Allen from their lives and block out his relationship with Soon-Yi Previn.
Farrow's second husband Andre Previn says Soon-Yi "does not exist" and their son, Fletcher, Photoshopped Allen out of every family photo and edited him out of family videos.
