Julianne Moore and Uma Thurman hung out together at a party for Waterford crystal in N.Y.C. Moore gave her friend a tour of the party space, which featured a tower of more than 500 champagne flutes. The ladies caught up on work and holiday plans before Thurman headed out to a late dinner with some producer pals. Moore stuck around, though, and mingled with partygoers like designer Christian Siriano.
