U.S. actress Mackenzie Phillips said in an interview with chat show host Oprah Winfrey that aired on Wednesday that she had an incestuous relationship with her father John Phillips, the late singer with 1960s band The Mamas & the Papas for years.
"I had tons of pills, and Dad had tons of everything too. Eventually I passed out on Dad's bed," Phillips read aloud during the interview from her book, "High on Arrival."
"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 and found myself having sex with my own father," Phillips further wrote in the book, which was the 13th highest selling book at online retailer Amazon.com.
Phillips, 49, starred in "One Day at a Time", wrote in the book that it happened while she was 19 years old, the night before her 1979 marriage to Jeff Sessler, a member of the Rolling Stones' entourage.
She added that she first tried cocaine at age 11, and that her father injected the drug into her arm for the first time when she was 16 or 17, "I remember going into my room, I was crouched on the floor," she said. "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."
