Courteney Cox tipped a valet and zipped off in her car after a meeting in LA yesterday. She's kept a busy social schedule this week — Courteney Cox and Brian Van Holt, her Cougar Town costar, were spotted enjoying drinks at the Malibu Inn recently. Courteney's estranged husband, David Arquette, meanwhile, had some fun of his own in Las Vegas with Kelly Osbourne over the weekend. David and Courteney have returned to their separate living situations since traveling the country to promote Scream 4, but the estranged couple were together on Easter. Courteney also had a run-in with old pal Brad Pitt recently at a party for their mutual friend.
