Dr. Drew Pinsky tells "Extra" the topic of Mackenzie Phillips' incestuous relationship with her father came up while shooting the upcoming season of VH1's "Celebrity Rehab." The addiction specialist breaks down the relationship between the 1960's rock star and his troubled daughter.
Dr. Pinsky says he and Phillips talked privately about the relationship, but out of respect for her family, she told him she didn't want those discussions televised.
"What's unusual about Mackenzie's case is there's a romantic quality to the relationship," Pinsky explains. He says her father assumed the role of "almost a cult leader where he was sort of using mind control over people and telling them that his way of seeing things was the right way," adding, "When you're a kid, you have no other way of seeing things and if you're then given drugs and addicted at the same time, it's hopeless for the young person."
Phillips declared on "Oprah" that she loved her father very much. Dr. Drew says, "She's been sober long enough that she can really reflect upon the fact that these were real feelings. This was somebody she really cares about and this was despicable situation."
Pinsky says incestuous relationships are more common than anyone can know, and there's an epidemic of childhood sexual abuse in America.
Season three of "Celebrity Rehab with Dr. Drew" is slated to premiere in early 2010.
