Chynna and Bijou Phillips Speak on Mackenzie Phillips Incest Allegations

by at . Comments

Her sisters are upset, her stepmom calls her a liar, but Mackenzie Phillips isn't backing down from her claim of a long-term sexual relationship with her dad.

She hopes to become the public face of incest, not a post anyone would want to hold, but one that represents an issue she says gets too little attention.

"If I've started a national dialogue that's going to help people face these issues, then I'm forever grateful," Phillips, 49, said Friday via satellite on Oprah.

Mackenzie Phillips, who revealed her shocking secret in a new memoir, High on Arrival, appeared for the second time this week on The Oprah Winfrey Show.

She returned to Oprah to face the doubts from her family about the nature of her relationship with John Phillips, founder of the band The Mamas and the Papas.

On Friday's show, Winfrey read comments made by John's ex-wife, Michelle, who was also a member of the band and later Mackenzie's stepmother:

"I have every reason to believe it's untrue," Michelle Phillips said, adding that Mackenzie has a history of mental illness and drug abuse.

Mackenzie Phillips, who also says she became pregnant, possibly with John's love child (which she aborted), didn't take the accusation sitting down, although she has by no means attempted to deny her long and troubled history of drug use.

"When Michelle found out I was writing the book, she vowed to do everything she could to discredit me," Phillips told Winfrey. "She's either protecting the Mamas and Papas brand or is having a textbook reaction: She's embarrassed."

Mackenzie's half-sister, Chynna Phillips, appeared live with Oprah and said that her mother, Michelle, is angry. "It's not something that my mom wants plastered all over the papers," she said, backing up her sister's side of the story.

But Chynna Phillips admitted she, too, shared some of her mother's sentiment: "Am I exceedingly joyful that my family secret that I told my therapist, my husband and my very best friend in the whole word [is now public]? No."

Nevertheless, she said, she has known about the situation for 12 years and, while she wasn't certain that her sister could be entirely accurate about the details, definitely believed that the two were sexually involved for a decade.

"I was completely stunned," she said when Mackenzie shared the secret. "I walked around in a comatose state for about 10 days."

Another sibling, Bijou Phillips, has released the following statement:

"When I was 13, Mackenzie told me she had a consensual sexual relationship with our father. This news was confusing and scary, as I lived alone with my father since I was 3, I didn’t know what to believe and it didn’t help that shortly there after Mackenzie told me it didn't happen .... "

"I understand Mackenzie's need to come clean with a history she feels will help others, but it's devastating to have the world watch as we try and mend broken fences, especially when the man in question isn't here to defend himself."


i've always admired mackinzie phillips, i liked her early movies. her dad was a fantastic songwriter(not much of a dad or family man). lots of that stuff that occured back then was augmented by drug use. i wish mackenzie well an hope she can heal from her wounds. where's your compasion folks?

@ homeboy1938

"consider the source" a drug addict and known pathological liar who tells about incest and repeats the stories of others as her own. When confronted, she says she was "joking" ...yes, joking. Then when she needs money and the publisher needs good stories to sell a book, she changes her mind and tells this story again. Now it has gone to a 10 year affair where her father wanted to marry her. Of course her father isn't here to defend himself. again consider the source. It is a shame that people are so eager to believe such crap about her father. Where is your compassion for a man whose daughter would lie and then joke about incest with him?


Mackenzie Phillips just wants to sell lots of books with shocking details that is most likely not true. You can't believe the words of a major drug addict that is broke and wants to make money. The man in question cannot defend himself. Even Bijou said that Mackenzie later told her it was not true. There are two sides to a story and we only hear one side.


I praise Mackenzie Phillips for telling perpetrators that they will be exposed! They can no longer count on their evil deeds being hushed up. This will save many young children from abuse by their parents. To parents who abuse children, I say, 'Shame on you! Stop it! Stop it now!'

@ Tony

my granny always said "consider the source". In this case you have a disturbed, broke, drug addict that needs to sell a book and make money. her father is dead and unable to defend himself. Her story just isn't credible.
