Last night was Hollywood's biggest party night of the year, the main event being the Academy Awards. However, there was plenty of celebrating happening outside the show. The Elton John bash, officially known as the 19th annual Elton John AIDS Foundation Academy Award Viewing Party, was one of the most stylish parties of the evening. Heidi Klum showed some seriously excellent legs in a thigh-high gown, and there was a white party between Claire Danes, Paz Vega, and Nicole Richie. Serena Williams and Kim Kardashian showed up in chic black, and there was the stuff of rock star legend with appearances from Prince and Steven Tyler. The Weinstein brothers, whose film The King's Speech took home best picture, also threw a bash that saw Jennifer Lopez in Marchesa. Click through our slideshow to see the stars' style!
