The lavish meal which took place at New York venue Indochine on Thursday evening last week was supposed to be for the fashion designer. Prabal and M.A.C. hosted the dinner to celebrate his recent Resort collection.
However, the Nepalese designer decided to turn the event into a birthday party for his long-time friend Zoe.
British singer Paloma Faith entertained guests with a lively performance, before Prabal surprised Zoe with a stunning birthday cake. The Hollywood star turned 34 on June 19.
Other famous faces to attend included Diane von Furstenberg, Liu Wen, Jenna Lyons, John Demsey, Joan Smalls, Chelsea Leyland and Olivier Zahm.
During the evening, Prabal addressed the guests and revealed he had always dreamed of traveling to New York.
“I grew up when all the supermodels were on the covers, and in Nepal I used to see Linda Evangelista, Christy Turlington, Cindy Crawford, and everyone, and I was like, ‘One day I will go to New York,’” he said.
