The American Ballet Theatre's Opening Night Spring Gala kicked off the organization's eight-week spring season at the Metropolitan Opera House in New York City last night. Celebrity fans of the ballet, including Lucy Liu (in Vivienne Westwood), Ashlee Simpson (in Alice + Olivia), and Uma Thurman (in Fendi), all adhered to the black-and-white dress code and enjoyed the two-hour performance of eight vignettes before heading to the Dior-hosted gala celebration to try their own dance moves on the black-and-white checkerboard dance floor. The dual color theme continued to the menu, too, which included Portobello mushroom and goat cheese appetizers and vanilla icing-topped chocolate cupcakes from Sprinkles to take home. “It was extraordinary!” Liu told InStyle.com of the night. “To see a compilation of all the best is really fun. I had an amazing time." And it was all for a good cause: The evening raised $1.75 million for ABT and the organization’s education and community outreach programs. Click the photo for more.
