Is Courteney Cox feeling sentimental this holiday season? More than two months after her amicable separation from David Arquette, the actress was snapped wearing her wedding ring (left) while visiting friends on Christmas Eve with 6-year-old daughter Coco. Just a few days earlier, Cox's digit remained bare during a "Cougar Town" holiday party, where, says E! Online, she stuck close to co-star Brian Van Holt. Despite hookup rumors (and Arquette's theory that Cox and Van Holt might have formed an "emotional" bond), the pair appeared more friendly than romantic. "There definitely wasn't any hand-holding or kissing," says a spy. "But they did stay and stand together for most of the party." Arquette, for his part, was sans ring as he partied away the night before Christmas at Los Angeles hot spot Voyeur.
