Mackenzie Phillips, the actress ("One Day at a Time") and daughter of Mamas and Papas founder John Phillips, has struggled with drug abuse and been in and out of recovery programs all her adult life. 

She was arrested last year at LAX, allegedly for cocaine and heroin possession, while on her way to a "Time" cast reunion in New York.

But on Oprah Winfrey's show Wednesday, Mackenzie finally tells the truth about who first got her into intravenous drugs — and even more shocking tales — when she was young.

Her father, John Phillips.

Dear Lord ….

We're gonna watch the show. Are you?
