Singer and actress Michelle Phillips, 65, says she's "so embarrassed -- and mad" about stepdaughter Mackenzie's recent revelations about incest with her father, John Phillips -- who was married to Michelle for eight years in the 1960s.
Sheila Weller interviewed Michelle for Vanity Fair two years ago, and called her for comment on the Mackenzie story. Michelle said she was also mad "At Oprah, at the publisher, and at Mackenzie, who should be on a psychiatrist's couch, not on TV."
In her new book, "High on Arrival," 49-year-old Mackenzie claims that she began an incestuous relationship with her father at age 19, which went on for ten years.
When asked if she thought the story was true, Michelle replied, "Is this all true? We'll never know, because she waited until John was dead," and voiced her concern about how the news will affect other members of the family, adding, "If you're going to make these accusations and they don't hurt anyone living, that's one thing. But Mackenzie has affected the lives of all her nieces and nephews, who are not going to school today and are staying home sobbing instead."
Weller also reports that an unnamed member of the "inner circle of the original Mamas and Papas" e-mailed her, saying, "If I could pull John out of his crypt and beat the crap out of him I would. What a tragic, disgusting, and disturbing piece of news."
High on Arrival is the #4 bestseller on Amazon today.
