Uma Thurman has gone public about her romance with model Elle Macpherson's ex ARPAD BUSSON, after turning up to a tsunami charity benefit hand-in-hand with the businessman. The new couple stepped out together at the Happy Hearts Fund charity event in New York on Wednesday (10Oct07), marking the first time the pair have posed for photographs in an official capacity since they started dating after meeting at a party in Italy in July (07). Twice-wed Thurman split from hotelier boyfriend Andre Balazs last year (06); Arpad was engaged to MACpherson for nine years before they split. Thurman wasn't the only star at the gala, set up to raise funds for supermodel Petra Nemcova's Happy Hearts Fund charity - Bruce Willis, Eva Mendes, Wyclef Jean and Nemcova herself also attended the bash.
