David Arquette shared some happy news on Twitter today. The Scream 4 actor shared:

“I have 100 days of Sobriety today!!! Life is beautiful. ”

David and estranged-wife Courtney Cox’s made a surprise announcement of their separation this past October after 11 years of marriage. Soon after the split became public Arquette displayed some questionable behavior on the “Howard Stern Show” where he spoke frankly about the troubles of their marriage. Topics on the radio interview ranged from the spouses’ lack of sex within their marriage to David’s brief sexual relationship with waitress Jasmine Waltz. Soon after the interview, David’s rep announced a statement that David entered a treatment facility for “alcohol and other issues.”

Since completing his treatment  and leaving rehab in January, David has been spending lots of time with his and Cox’s daughter, Coco, and with Cox, most recently posting a picture of the trio at Walt Disney World.

Congratulations David!
