Mackenzie Phillips Slept with her Father

People reports that Mackenzie Phillips, 49, of One Day at a Time fame, had a long term incestious relationship with her father.  Mackenzie documents in her new book High on Arrival, which comes out tomorrow, that the relationship became consentual and that she doesn't want people to hate her late father.  Mackenzie's father was John Phillips of the Mama's and the Papas, he died in 2001.  I suddenly understand all of Mackenzie's drug issues.    She was last arrested one year ago for possession of cocaine and heroin at an airport.
