If they weren't friendly during their separation, then David Arquette and Courteney Cox definitely aren't friends now. The two married in 1999 and got separated in October 2010, and Arquette filed divorce documents last Friday. TMZ reports that Arquette signed the papers back in March and has been holding on to them for nearly three months. When they separated, the pair, who met on the Scream set, released a joint statement at the time: "The reason for this separation is to better understand ourselves and the qualities we need in a partner and for our marriage." It looks like that never happened, nor did the reconciliation Arquette had hoped for. The two appeared on Howard Stern's radio show last year, and Arquette was clear that he did want to reunite, but Cox was less than enthusiastic about reconciling.
