"Shooting the Cougar Town season finale with @IBGomez @davidarquette and @ChristaBMiller," Twitter newbie Courteney Cox wrote, reinforcing that they are currently the ones to beat in Hollywood's Most Friendly Exes competition.

David is rumored to be playing -- spoiler alert! -- a hotel concierge who caters to the Cul-de-Sac crew's wildest needs while Jules & Grayson prep for their wedding!

Although this isn't David's first time playing waitstaff -- he recently co-starred with Uggie in an ET exclusive video!

Cougar Town (finally!) premieres on February 14 on ABC.
