In an interview on "The Joy Behar Show," Phillips said, "I'd like to reframe my word consensual."

She continued, "As I was writing the book, I thought, this word, it kept sitting wrong with me. But I used it for lack of a better word. Since then, I've been schooled by thousands of incest survivors all across the world that there really is no such thing as consensual incest due to the inherent power a parent has over a child. So, I wouldn't necessarily call it a consensual relationship at this time."

Phillips appeared on the show with Dr. Drew Pinsky to talk about their VH1 show, "Celebrity Rehab." Dr. Drew said incest cannot be consensual.

"The child is trying to make sense of this situation she feels as though the only she can survive it is by saying, 'I'm creating it, I have some power in this, I'm consenting to it,'" Dr. Drew explained. "When the fact is, the kind of relationship a parent has with a child makes consent actually impossible."

In "High on Arrival," Phillips wrote about having sex with her father, John Phillips of the Mamas and the Papas -- including on the eve of her wedding. The secret relationship continued for 10 years.

Sex addiction has been catapulted into the headlines with the Tiger Woods scandal, and the reality TV show "Sex Rehab with Dr. Drew."

Addiction specialist Dr. Drew Pinsky and therapist Jill Vermeire tell "Extra" that in order to overcome an addiction, you first have to admit there's a problem, but will sex rehab work for Woods?

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.

Addiction specialist Dr. Drew Pinsky tells "Extra" he's "convinced" Adam "DJ AM" Goldstein got re-hooked on drugs after doctors prescribed pain medication for his injuries in a September 2008 plane crash.

Pinsky tells "Extra," "I'm convinced that after his plane accident he was probably -- appropriately -- given some anti-anxiety medicine and sleep medicine and then just stayed on it."

Dr. Drew was a close friend of AM's and explains how a former addict can fall back into the world of drug abuse. "It's remarkably easy. All you have to do is be exposed to the chemicals," Pinsky says. He adds, "If you're not prepared for what happens, if you aren't honest about it, if you don't prepare the recovering support you have around you, it can be a disaster."

The doctor is still coming to terms with the late star's death. Dr. Drew says he's confident the post-traumatic stress of surviving a deadly plane crash and DJ AM's recent breakup would not have resulted in a relapse if AM hadn't been taking medication.

Dr. Drew Pinsky has revealed that he believes the pain medication prescribed to DJ AM after his plane crash may have lead him away from sobriety.

"It very slowly and subtly reawakens addiction," Pinsky told AP. "I'm not saying it was inappropriately prescribed, I'm saying he didn't know the risks."

Pinksy, the host of "Celebrity Rehab," grieved the death of the disc jockey in the interview, saying that he was "very close" to Goldstein, who had been an outspoken advocate of rehabiliation after coming clean about past addictions to crack cocaine and Ecstasy.

Drew also praised Goldstein as a "model" for people who are trying to kick drugs -- and said that AM was "selfless" when it came to helping others kick their addictions. "He sponsors other people, and in his words, will go to the mat supporting people on their recovery," Pinsky said. "He was a very supportive recovery person. He was someone I referred people to, to learn about recovery."

Adam, like Dr. Drew, filmed a show centered on rehab called "Gone Too Far," and features DJ AM intervening in the lives of young people who are struggling with addiction. MTV, who had originally planned on airing the series in October, has stated that the future of the show is up in the air.

The doc dismisses claims that Adam's reported relapse was caused by being around drug addicts while filming the show. "That's not in any way the kind of thing that leads to someone relapsing."

Due to Adam's history with battling drug addiction, Dr. Drew finds the circumstances surrounding the death of AM shocking. "It was so much of a surprise I have a hard time believing it."
