An actress claims she was disowned by her family after alleging her musician father raped her.

Mackenzie Phillips, 57, claimed her father John Phillips, of The Mamas & The Papas, abused her for ten years.

In her new book, the One Day At A Time star gave more details about the effect on her family life, saying relatives blamed her for going public and were upset that her father could not defend himself against allegations.

She claimed one family member, who is not named, even disinvited her to a birthday party.

‘She wouldn’t forgive me! For abuses perpetrated against me as a child, or for exposing those abuses perhaps,’ she wrote.

In 2009, Phillips claimed her father raped her at age 19 while they were both under the influence of drugs and alcohol.

‘Papa’ John was a singer and songwriter of The Mamas & The Papas – the sixties band famous for hits like California Dreamin’ and Monday, Monday.

He died in 2001 after a long battle with drugs and alcohol.

But before his death, Phillips claimed she confronted her father about the rape, but he responded: ‘You mean when we made love?’

In her book, ‘Hopeful Healings: Essays on Managing Recovery and Surviving Addiction’, she said her family have been supportive throughout the ordeal, but some members still blame her for the abuse.

She wrote: ‘I’ve come to understand that some in my family have chosen to hold on to the pain and anger they felt when I came out with the truth about my dad.

‘I’ve also had to accept that, of course, I’d be the target of negative reactions and feelings because I’m the one who wrote the book and told a truth no one wanted to hear.’

She also recounts her 2008 arrest for heroin possession, the sexual abuse and life now as a drug rehab counsellor at Breathe Life Healing Center in California.
