Dylan Farrow, the adopted daughter of actress Mia Farrow and director Woody Allen, has made sexual abuse claims against her famous father.

For 20 years she hasn't spoken publicly about her allegations but now she's breaking the silence.

Speaking to the Vanity Fair writer who originally reported on the case in 1992 Dylan says she's still scared of her adoptive father, who she says molested her at age 7.

'I have never been asked to testify. If I could talk to the seven-year-old Dylan, I would tell her to be brave, to testify,' Dylan told Vanity Fair.

'There’s a lot I don’t remember, but what happened in the attic I remember. I remember what I was wearing and what I wasn’t wearing,' she continued.

'The things making me uncomfortable were making me think I was a bad kid, because I didn’t want to do what my elder told me to do.' What Allen allegedly did to her in the attic pushed her over the edge she says.

'I was cracking. I had to say something. I was seven. I was doing it because I was scared. I wanted it to stop.'

Farrow said she even thought that this was how fathers treated their daughters. 'This was normal interaction, and I was not normal for feeling uncomfortable about it.'

But Woody Allen’s lawyer Elkan Abramowitz says that Allen still denies the allegations of sexual abuse.

Mia and her children are the subject of Vanity Fair's November issue, in which eight of her 13 children talk enthusiastically about the diversity of their upbringing.

Mia's son Ronan told Vanity Fair: 'I am so proud of my family. I grew up across the table from Moses, who has cerebral palsy, and next to my sister Quincy, born of a drug-addicted inner-city mother, and Minh, who is blind. I could never have understood what it means to grow up blind or with cerebral palsy. I saw problems and needs, so the next thing you think is: O.K., what are you going to do about it?'

The Vanity Fair profile also reveals that Ronan might instead be Frank Sinatra's son:

Farrow candidly discusses her relationship with Frank Sinatra in the new article, explaining that Sinatra was the great love of her life, and adding,'We never really split up.'

When asked if her son with Woody Allen, Ronan Farrow, may actually been Sinatra's Farrow answers, 'Possibly.'

To date no DNA tests have been done. When Nancy Sinatra Jr. is asked by the magazine about Ronan’s being treated as a family member, Sinatra answers, 'He is a big part of us, and we are blessed to have him in our lives.'
