During an appearance on Piers Morgan’s CNN talk show, Ryan O’Neal, 70, launched into a bizarre bit of speculation that he and his children may have caused his longtime partner Farrah Fawcett‘s death from anal cancer. He reasoned that Farrah was very health conscious and never smoked, so he believes the stressful relationship he has with his children, and especially Tatum O’Neal, could have been the reason Farrah developed cancer. Ryan said: “What bothers me the most is that there was turmoil during my love affair with Farrah, a lot of it caused by my family and my kids. All of them, but particularly Tatum. And I just think that if she had never met us, would she still be alive today? Because nobody knows what causes cancer.” According to Tatum, Ryan, a longtime substance abuser, apparently encouraged his four children, including Redmond O’Neal, his son with Farrah, to use drugs. After the interview aired, Tatum wrote on Twitter: “My dad is both the aggressor and the victim. You can’t be both” and “having lived with this type of person during my formative years took a terrible toll on me and my bro.” Later she added, “I really don’t know how we survived to tell u the truth. Peace.”
