David Arquette has checked himself into rehab. Of course he partied like an animal throughout the holidays. He has been on a bender since his recent split from Courtney Cox. I seriously doubt that his alleged drinking issues are new, just more out of control since the break up. David has always been a wild and crazy guy and I'm sure that wore thin on the more serious (seeming) Courtney. Not to mention the age difference. Let's hope David can get a grip and get it together at least for the sake of their child Coco.
