The Scream star completed a four-week program in a rehabilitation facility in January after entering the venue over the New Year weekend to receive treatment for "alcohol and other issues," following his separation from actress Courteney Cox in October last year.

Arquette has since undergone a lifestyle overhaul, competing on  talent show Dancing with the Stars and moving on with a new girlfriend.

Now, the star has reached 365 days alcohol-free, even refusing to take medication following a car crash in March in order to stay clean.

In a post on Twitter.com, Arquette writes, "Today marks 1 year of sobriety for me. I thank God for the strength and guidance and my family and friends for their love and support & I TY (thank you)."
