Former child star Mackenzie Phillips told Oprah yesterday that her father, John Phillips of the 1960s folk group the Mamas and the Papas, had sex with her beginning when she was 19 years old. She called the relationship a "betrayal." Now 49, Mackenzie starred in George Lucas's 1973 film American Graffiti at 13, then when she was 14, shot to stardom on the long-running sitcom One Day at a Time. During her time on the show, it became clear that she had a drug problem and was written out so she could go to rehab. She has been in and out of rehab ever since and was arrested last year for possession of cocaine and heroin. She's just released a memoir entitled High on Arrival, in which she talks about her first sexual encounter with her father, when they were both high on drugs, writing, "I woke up that night from a blackout to find myself having sex with my own father."
Mackenzie claims it was rape, but admits they later had consensual sex over a period of ten years. "Over time your perception of things become warped and twisted," she said, adding, "I'm not [talking about this] to make myself look good. There's no way I'm going to look good. I was old enough to know better." Mackenzie says she put a stop to it when she had an abortion, because she was unsure if the baby was her father's. She told Winfrey, "I never let him touch me again," calling the alleged incest "an abuse of power." In the book, she wrote: "Your father is supposed to protect you. Not f- - - you." She also alleges that Mick Jagger cornered her in a room and seduced her when she was 18, saying, "I've been waiting for this since you were 10 years old." Mackenzie goes on to say John taught her to roll a joint when she was 13 and that when she was 17, he started her on hard drugs. "My father shot me up for the first time... He tied me off and he put the needle into my arm and pushed the plunger in, and he missed, he missed the vein and my whole arm went numb. He seemed a little nervous but at the same time it seemed very commonplace."
