Mackenzie Phillips, on the promotional trail for her book, High On Arrival, said on the Today Show Thursday that her father, The Mamas And The Papas singer John, was "not a bad man, just a very sick man," despite engaging her in an incestuous relationship throughout her twenties.
The child star of American Graffiti and One Day At A Time fame --who has battled drug addiction for years -- said that she only realized what had happened after waking up in her father's bed the morning of her wedding with her pants down around her ankles, adding that the sex "wasn't consensual by any stretch of the imagination."
She said after two years of being molested, she began letting her father make love to her consensually. Phillips said the last straw to all the sex she was having with her dad was a paternity scare after she got pregnant while she was married.
"I got confused, and I never let him touch me again," she said, adding her father graciously paid for the abortion.
