Naomi, Hugh and Isla Horse Around for Haiti and More!
Master of Ceremonies Hugh Jackman welcomed fellow Aussies Naomi Watts and Isla Fisher to the fourth annual Veuve Clicquot Polo Classic on New York City's Governors Island. Taking a brief break from her summer vacation to attend the event (which raised funds for The Urban Zen Foundation's Hope, Help & Rebuild Haiti initiative) Watts discussed her love of the sport of kings. "I don't know much about the finer points," the actress admitted. "But I did date a polo player a long time ago."
