Mackenzie Phillips: My Father Shot Me Up For the First Time

In a new tell-all interview, "One Day at a Time" child star Mackenzie Phillips discloses to Oprah Winfrey shocking details of her unhealthy relationship with her father, her drug use and an alleged sexual encounter with The Rolling Stones' frontman Mick Jagger.

"My father shot me up for the first time," Phillips reveals on a promo for "The Oprah Winfrey Show." She recalls her father only being slightly nervous when he injected her with cocaine, saying it seemed to be the "next logical progression."

"I remember going into my room, I was crouched on the floor. ... He put the needle in my arm and put the plunger in and he missed. He missed the vein and my whole arm went numb."
