Mackenzie Phillips: I Slept with My Own Father
"Don't hate my father," Mackenzie Phillips tells PEOPLE.
But in a tell-all book out Wednesday, the former childhood actress reveals that her dad, musician John Phillips of the '60s band the Mamas and the Papas, engaged with her in a long-term incestuous relationship.
Phillips, 49, who has survived drug addiction, arrests and divorce, writes in the book High on Arrival that she was already a star playing a boy-crazy teen on the TV sitcom One Day at a Time when her father had sex with her on the night before she was to marry Jeff Sessler, a member of the Rolling Stones entourage, in 1979.
"On the eve of my wedding, my father showed up, determined to stop it," writes Phillips, who was 19 and a heavy drug user at the time. "I had tons of pills, and Dad had tons of everything too. Eventually I passed out on Dad's bed."
"My father was not a man with boundaries. He was full of love, and he was sick with drugs. I woke up that night from a blackout to find myself having sex with my own father."
"Had this happened before? I didn't know. All I can say is it was the first time I was aware of it."
Phillips' life began to spiral out of control. In 1980, she was fired from One Day at a Time because of her constant drug use. That same year, she went to rehab – with her father. Her sexual relationship with him had become consensual.
