Mackenzie Phillips’10-year-long sexual relationship with musician dad John Phillips
This is one heck of a messy – and incestuous – relationship between father and daughter. American actress-singer, Mackenzie Phillips, had sex with her musician father, John Phillips (from The Mamas & the Papas), on the eve of her first wedding in 1979, when she was 19. She claimed that it all happened under the influence of drugs and that the sexual relationship between them – which spanned for a total of 10 years – was a “consensual” one. Due to her history of drug abuse and mental illnesses, Mackenzie’s tell-all in 2009 was cast with doubts by family members who remain divided over its authenticity.
