His very public downward spiral seemingly complete, David Arquette has checked himself into rehab. The 'Scream' actor, who announced his split with wife Courteney Cox in October, sought help some time over the New Year's weekend after months of erratic behavior. His rep confirmed the news to PEOPLE.

According to TMZ, which broke the story, Arquette checked into an unnamed live-in rehab facility to address an alcohol problem. The actor hosted a New Year's Eve party at Arquette & Beacher's Madhouse Theater, located at the Roosevelt Hotel in Los Angeles. According to its website, the venue features a "Flying Midget bartender" and has the "atmosphere of a circus."
