Mackenzie Phillips made the shocking revelation in her explosive new memoir 'High On Arrival'. She writes that her first sexual encounter with the musician happened the night before she married Jeff Sessler, who was a member of the Rolling Stones entourage. She writes, "I had tons of pills, and Dad had tons of everything too. Eventually I passed out on Dad"s bed."
She says her father was not a man with boundaries. He was full of love, and he was sick with drugs. One night, she woke up to find herself having sex with her own father. She says she does not whether it was the first time. But it was the first time that she was aware of it. For a moment she was in her body, in that horrible truth, and then she slid back into a blackout.
She writes further, "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."
However, John Phillips was the chief songwriter and leader of the singing group 'Mamas And The Papas'. He was married to Susan Adams and was the father of Jeffrey Phillips, Mackenzie Phillips, Chynna Phillips, Tamerlane Phillips, and Bijou Phillips. He died eight years ago.
