Seems like the poor guy isn't handling his split from Courteney Cox as well as one would've hoped.

David Arquette has entered into a rehab program, his rep confirms. And while there is no more official information, it's probable that the 39-year-old dad's recent actions have been questionable at best...

Arquette recently admitted on Howard Stern's radio show that, following his separation from wife Courteney Cox in October of last year, he's been "drinking a lot."

The troubled actor also claimed that his psychologist believed he was having a "nervous breakdown" and that "everybody's worried and concerned about me."

Let's hope Arquette finally gets the help he needs to cope with this obviously traumatic experience. We're rooting for you, David!
