It's no wonder MacKenzie Phillips has led a life of self destruction and drugs.
In her shocking memoir, High On Arrival, out on Wednesday, Phillips reveals details on having an incestuous affair with her father, who also shot her up with cocaine for the first time.
She claims her father, John Phillips of the 60's band Mamas and the Papas, first had sex with her on the eve of her wedding to Jeff Sessler, a member of the Rolling Stones entourage.
The former child star claims that the affair was a long-term one and that her father even suggested they run away somewhere "where no one would look down on us. There are countries where this is an accepted practice. Maybe Fiji."
MacKenzie is on The Oprah Show Wednesday to talk about her new book and it's explosive revelations.
She talks on the show about her father shooting her up with cocaine for the first time, saying, "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."
MacKenzie also talks about her affair with Mick Jagger at age 18, saying, "Mick Jagger locks the door and he says 'I've been waiting for this since you were ten years old.'"
