Tatum O'Neal Hit on by Father Ryan at Farrah Fawcett's Funeral

Ryan O'Neal admits that he was so frazzled at Farrah Fawcett's funeral that he hit on his own daughter, Tatum O'Neal.

“They had just put the casket in the hearse and I was watching it drive away when a beautiful blonde woman comes up and embraces me," Ryan tells Vanity Fair. "I said to her, 'You have a drink on you? You have a car?' She said, 'Daddy, it's me -- Tatum!' I was just trying to be funny with a strange Swedish woman, and it's my daughter. It's so sick."

Both Tatum and her brother Griffin O'Neal also speak to Vanity Fair of Ryan's failures as a father, his rages and his drug use.

"My father is afraid of me because I know the truth," Griffin says. "That's the part that absolutely scares him to death." Griffin suggests that the family's problems might have something to do with the fact that Ryan plied his children with drugs -- "My father gave me cocaine when I was 11 and insisted I take it. ... He was violent all the way through my upbringing," says Griffin. "He was a very abusive, narcissistic psychopath. He gets so mad he can't control anything he's doing."


Phillips: "Beatings, hunger, neglect, sexual molestation, underage drinking, underage driving, car crashes, suicide attempts, and drugs virtually everywhere."

O'Neal: "I thank God everyday that it is so behind me."

Phillips: "What made you want to share so many painful secrets about your life and family?

O'Neal: "I think it's a chance to say, you know, things don't just happen by accident. One doesn't just fall off the edge of a cliff for nothing."

It was a spectacular fall from the heights of Hollywood stardom, as the youngest Academy Award winner in history, to a desperate drug addict who'd lost control of her life and custody of her children. Tatum O'Neal's new memoir, "A Paper Life," is a story about damaging childhood experiences that instilled "a profound self-loathing and sense of worthlessness." But it's also a story of survival, about a gutsy little girl forced to rely on wits and determination when adults let her down -- much like the orphan she played in the movie that made her famous.

But the bigger question is whether Ryan's devotion to Farrah in her last days was just an act.

His son Redmond thinks it was.

 "All those crocodile tears! ... My dad's only goal was to make sure he would be in the will,” Redmond tells Vanity Fair. "It was so disgustingly transparent as soon as he found out she was terminal. I consider him a vulture presiding over a carcass. Ryan thought he was going to get everything."
