This afternoon, Mackenzie Phillips revealed on Oprah what most of the world found out earlier this week—that Phillips had a 10 year affair with her father, John Phillips of the Mamas and the Papas.
In her new book, High on Arrival, Phillips chronicles her life of drug, sex, rehab, divorce, arrests, and a sexual relationship with her father. The affair, which was a consensual relationship, began on the evening before her marriage to Freddie Sessler, when Phillips was just 19 years old.
