Mackenzie Phillips Reveals Incestual Affair With Her Dad, John Phillips

One Day At a Time star Mackenzie Phillips claims in a new book that she had a 10-year, incestuous relationship with her father, Mamas and Papas singer John Phillips.

The former child star told People that her father first had sex with her, when she was 19, on the night before her wedding (to Rolling Stones entourage member Jeff Sessler). Both father and daughter struggled with drug addiction, and eventually their sexual relationship became consensual. John died in 2001.


Mackenzie Phillip's tell-all book, High On Arrival, is out today. Her interview with Oprah also airs today.

Mackenzie's half-sister, Chynna Phillips (from the '90s pop band Wilson Phillips) also shares her side of the story, telling US Weekly that she believed the story and went into a deep depression after learning of the affair.

What a heart-breaking story. Do you think Mackenzie Phillips is brave for sharing her story? Or should some things remain private?
