Mackenzie Phillips Says She Had Sex With Her Father

Troubled former One Day at a Time actress Mackenzie Phillips is coming clean about her relationship with her father, The Mamas & the Papas founder John Phillips. And the details aren’t pretty.

People magazine has published excerpts from Phillips’ upcoming biography, High on Arrival, in which she reveals that she had a long-term incestuous relationship with her dad.

As Philips, 49, writes, the relationship began in 1979, the day before Phillips married Jeff Sessler, a member of the Rolling Stones’ entourage. Phillips, who admits that she was a heavy drug user at the time, was an easy target for Papa John: 

“On the eve of my wedding, my father showed up, determined to stop it. 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.”

Phillips continues,

“Had this happened before? I didn’t know. All I can say is it was the first time I was aware of it.”

But it would be far from the last time it occurred. Phillips goes on to write that by the following year, 1980, the relationship had become consensual.

This isn’t the only disturbing revelation that Phillips has made about her father recently.

In an interview scheduled to run on Wednesday’s episode of The Oprah Winfrey Show, she reveals that dear ol’ Dad was the first person to shoot her up with drugs, injecting her with cocaine:

“My father shot me up for the first time…I remember going into my room, I was crouched on the floor. … He put the needle in my arm and put the plunger in and he missed…He missed the vein and my whole arm went numb.”
