Now We Know Why Mackenzie Phillips Has Issues

Mackenzie Phillips reveals in a new book that she slept with her own father.

“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.

He was full of love?

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. She even toured with him in a band called the New Mamas and the Papas. Her sexual relationship with him had become consensual.

“One night Dad said, ‘We could just run away to a country where no one would look down on us. There are countries where this is an accepted practice. Maybe Fiji.’

“He was completely delusional. No, I thought, we’re going to hell for this.”
