David Arquette suit three peice suit crying separated divorce Courteney Cox

We're not sure if he partied a little too hard on Halloween or what (he HAS admitted to hitting the bottle since his separation from Courteney Cox), but David Arquette was definitely in a mood when we snapped him out and about in Beverly Hills yesterday.

The 39-year-old actor was wearing one of his trademark suits, but rather than smiling like he always does, he kept his head down as he rocked out to his iPod. Wonder what sorts of tunes he was listening to? Maybe we can blame his mood on the music?
