QUICK TAKES - Sept. 24, 2009

Former child star Mackenzie Phillips said Wednesday that she had a decade-long sexual relationship with her father, pop superstar John Phillips, who also taught her how to roll joints and injected her with cocaine.

Mackenzie Phillips, 49, writes in her new book, “High on Arrival,” that she had sex with her father on the night before she was to get married in 1979 at age 19.

John Phillips, who died in 2001, was the leader of the 1960s group the Mamas and the Papas.

She said on “The Oprah Winfrey Show,” in an interview that aired Wednesday, that the sexual relationship with her father ended when she became pregnant and didn’t know who had fathered the child. She had an abortion, which her father paid for, “and I never let him touch me again.”

Winfrey read a statement from Genevieve Waite, John Phillips’ wife at the time of the alleged abuse and Mackenzie’s stepmother. Waite’s statement said John Phillips was “incapable, no matter how drunk or drugged he was, of having such a relationship with his own child.”
