David Arquette celebrates 100 days of being sober

David Arquette has been sober for 100 days.

The 'Scream 4' actor says he has been clean since checking out of the Betty Ford Center - where he underwent rehabilitation treatment for alcoholism - at the end of January and is starting to the joys of life again.

He tweeted today (07.04.11): "I have 100 days of Sobriety today!!! Life is beautiful.:D (sic)"

David has previously revealed his estranged wife Courteney Cox and his actress sister Patricia Arquette were responsible for the intervention that resulted in him checking into rehab.

The 39-year-old actor - who raises a six-year-old daughter Coco with the former 'Friends' star - said: "I came back from Miami and I had taken a nap and I woke up and Patricia and Courteney were at my bed. I was like, 'What are you two doing here together?'

"Then I walked out and my best friend was there, my business partner and some guy I don't know, and I go, 'What up, turkeys? I guess this is my intervention.' "

He also admitted to drinking his first beer when he was just four years old.

He said: "I must have been four years old. I was down in the basement with my dad and the beer was there and I just grabbed it and drank it. I remember that. It's one of my earliest memories."
