Naomi Watts and her fellow Australians Hugh Jackman and Isla Fisher, in D&G, were among the celebrities who turned out for the Veuve Clicquot Polo Classic on NYC's Governors Island yesterday. Nicky and Kathy Hilton were also on hand at the sporting grounds, where polo player and Ralph Lauren model Nacho Figueras showed off his skills on the field. Hugh sang a version of "Take Me Out to the Ballgame" to kick off the fourth annual match before taking his seat along the sidelines. Nacho's Black Watch team won the game, and once his work as an athlete was done, he changed into a Summer suit to enjoy the rest of the afternoon. The champagne was flowing at the Sunday soiree, and Donna Karan got the party started by teaming up with Wyclef Jean on the dance floor. Wyclef performed and lent his support to the event, which also served as a fundraiser for Donna's Hope Help & Rebuild Haiti nonprofit.
