According to Gossipcop.com, Mackenzie Phillips tells Oprah that she had sex with her father, John Phillips.
So apparently her shocking family secret isn’t as boring as we initially thought.
"I had sex with my own father," the website quotes her as saying.
She continues to say that he shot her up with drugs and raped her.
In her new memoir "High on Arrival," she details what happened when she later confronted him:
"We have to talk about how you raped me." He responded, "You mean when we made love?"
John Phillips passed away in 2001.
