While most of the New Moon cast was at the official afterparty following last night's screening in New York, Robert Pattinson and Kristen Stewart slipped away for some private quality time. Rob and Kristen were over at Avenue, holding court at a table upstairs with a bodyguard making sure people gave them their privacy—but no such luck. Rob, trying to go incognito, wore a baseball cap. The costars were sitting right next to each other and kept whispering in each other's ears and laughing together. At one point, Kristen started stroking Rob's back.
