NEW YORK - David Arquette's publicist says the actor has checked out of rehab.

In an email Monday to The Associated Press, Cindy Guagenti confirms the 39-year-old actor left Sunday after completing treatment for alcohol and other problems. He entered an undisclosed rehab centre nearly a month ago.

Arquette and Courteney Cox announced their separation in October after 11 years of marriage. They have a 6-year-old daughter, Coco.

The couple met on the set of the movie "Scream" in 1996 and married three years later. They are co-starring in the fourth installment of the "Scream" series, due out this year.

Arquette co-starred with Drew Barrymore in the 1999 romantic comedy "Never Been Kissed."
