Famous Incest Stories: John And Mackenzie Phillips

Legendary American folk-rock group The Mamas & The Papas were icons of the 1960s. Their chart-topping hits “California Dreamin'” and “Monday Monday” still play on the radio to this day.

John Phillips was the leader of the group and composed a majority of their vocal arrangements. He was idolized by many and maintained a charming public image throughout his career.

However, in 2009, nearly a decade after Phillips had passed away, his daughter, Mackenzie, went public with tales of the incestuous relationship between her and her father that began when she was just 19 years old.

On the eve of her first marriage, Mackenzie and John partook in a serious narcotics binge and Mackenzie blacked out. Mackenzie allegedly woke up to her father having sex with her, and the drug-induced affair carried on for ten years.

The relationship ended when Mackenzie became pregnant and feared that John was the father of her child. In her book High on Arrival, she states that her father paid for the abortion and the incestuous relationship finally came to an end.
