It has not been a good week for Ryan O'Neal. The widower of Farrah Fawcett recently admitted to accidentally hitting on his own daughter at Fawcett's funeral and now his son from his first relationship is claiming O'Neal ruined his life by giving him cocaine at the age of 11...

So far, he's making Jack Tweed look like a saint...

O'Neal's eldest son from his first marriage to to Joanna Moore, told Larry King that his father destroyed his life by offering him drugs during his childhood.

I was 11 years old when he gave me cocaine and said we are going to see a long movie called Barry Lyndon. He said 'It is a very long movie. Maybe this will help you'. I was 11. I could never, never ever do that to my child.

Griffin also told King that O'Neal only reconciled with Fawcett months before her death from terminal cancer, so that he would be in the will.

He added:

All those crocodile tears! My dad's only goal was to make sure he would be in the will.

Fawcett and O'Neal's own child, Redmond, 24, is currently in prison for drug offences and their eldest, Tatum, is finally clean from drugs after being arrested for trying to buy crack cocaine on the street last year.

O'Neal recently admitted that when Tatum arrived at Fawcett's funeral, he tried to chat her up:

I 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.

I was just trying to be funny with a strange Swedish woman and it's my daughter. It's so sick.

We have to admit that none of this is particularly pleasant. But trying it on with your daughter at your wife's funeral is probably the 'sickest' part...
