Fresh off his stint in rehab, David Arquette is ready to come clean about his alcohol and drug-riddled past.
Sober since December 29, the 39-year-old Scream 4 actor opens up to Oprah Winfrey during a Thursday appearance on her daytime talk show (check your local listings).
"When I had my first drink of beer, I must have been four-years-old," he tells Winfrey, 57. "I was down in the basement with my dad and beer was there and I just grabbed it and drank it. And I remember that. It's one of my earliest memories."
According to the actor, he voluntarily checked into rehab on January 2 at the insistence of his sister, Patricia Arquette, and his estranged wife, Courteney Cox (with whom he shares a six-year-old daughter, Coco).
"I came back from Miami and I had taken a nap. I woke up and Patricia and Courteney were at my bed," he recalls. "Courteney had a cup of coffee. I was like, 'What are you two doing here together?' I already knew."
"Courteney's like, 'Do you mind coming out to the living room for a minute?' I said, 'Sure, let me get dressed.' I put on this white outfit and came out. I peeked my head out and [I saw] my best friend Hartwell and my business partner and some guy I don't know. I go 'What up, Turkeys? I guess this is my intervention!'"
Since seeking treatment, a source tells UsMagazine.com that Arquette and Cox, 46, "are still great friends and getting along really well."
