Mackenzie Phillips Family Secret Revealed on Oprah: Sex With Her Father (VIDEO)

Mackenzie Phillips reveals her explosive family secret on Oprah, telling the talk show host, "I had sex with my own father."

The interview coincides with the release of the former "One Day at a Time" star's memoir, "High On Arrival."

Mackenzie says her father, The Mamas and the Papas founder John Phillips, introduced her to drugs, shooting her up for the first time. She also details being seduced by Mick Jagger when she was 18. But the biggest bombshell she reveals is that she was raped by her father when she was 19, as she faded in and out of consciousness.

"On the eve of my wedding, my father showed up, determined to stop it," Phillips wrote. "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."

She later confronted him, saying "We have to talk about how you raped me," to which he responded, "You mean when we made love?"

The memoir reveals the two had a long-term incestuous relationship. John Phillips died in 2001. Mackenzie, 49, has battled drug addiction and trouble with the law since she was a teenager.
