Mackenzie Phillips isn’t holding anything back.

More than seven years after the former One Day at a Time star came out with details about her incestuous relationship with her late father, John Phillips, during an interview with Oprah Winfrey, she has sat down with the famed talk show host about her troubled past.

“I felt like I was sort of in abject terror,” the 56-year-old said. In her book, she alleged her father raped her when she was 19-years-old — noting that, at the time, they were both under the influence of drugs and alcohol.

In the course of a decade to follow, the sexual relationship continued on-and-off, eventually becoming what she described as “consensual.”

“I felt like, here I was with this huge piece of information that maybe wasn’t even fit for public consumption,” she said Oprah: Where Are They Now?. “I hadn’t done my due diligence. When I wrote the book, I just thought, ‘I’m not gonna Google this, I’m not gonna Google that. I’m just going to tell my story as it happened to me.’ But then, in retrospect, there was some due diligence that I missed doing. Like preparing myself for losing my family.”

Mackenzie Phillips currently works at Breathe Life Healing Centers as a Substance Use Counselor.
