Yesterday, I told you about Mackenzie Phillips interview with Oprah which is sitting on my DVR waiting for me.  As I mentioned, Mackenzie admits to having sex with her father.  I was unclear as to the circumstances, but reading about today's interview has cleared up any fuzziness that I may have been experiencing. Mackenzie told the audience that she had sex with her father starting at the age of 19 -- she told Oprah that it was "an abuse of power".  The night before her wedding, she got totally high with her dad and passed out.  When she woke up, her father was having sex with her.  And this sexual relationship continued for ten years!  At one point, her father even suggested that they move to Fiji where father-daughter affairs are apparently more accepted. Then there's the matter of truth.  Is Mackenzie lying about all this to sell books?  John Phillips wife at the time of this alleged "affair" thinks so.  According to Genevieve Waite, John was "incapable, no matter how drunk or drugged he was, of having such a relationship with his own child."  Another of Mackenzie's step-mothers also thinks she's lying.  Michelle Phillips, co-founder of Mamas and Papas had this to say:  "I think it’s unconscionable that Oprah would let her do her show. I have every reason to believe it’s untrue. Oprah should be more judicious about who she has on her show.”  She does have some family support, though.  Chynna Phillips, half-sister to Mac and daughter of Michelle, claims that she was told about the inappropriate union back in 1997.  She told Us of her reaction:  "Somebody could have dropped a piano on my head and I probably wouldn't have felt it.  But I knew it was true. I mean, who in their right mind would make such a claim if it wasn't true?" After a decade of having sex with her dad, Phillips became pregnant.  She says she doesn't know who the father was, but she had an abortion that John paid for.  After that, she never had sex with him again. Phillips concluded by saying, "I can't be the only one this has happened to.  Someone needs to put a face on consensual incest." />Yesterday, I told you about Mackenzie Phillips interview with Oprah which is sitting on my DVR waiting for me.  As I mentioned, Mackenzie admits to having sex with her father.  I was unclear as to the circumstances, but reading about today's interview has cleared up any fuzziness that I may have been experiencing.
