Is It Even a Birthday Party Until Kate Moss Jumps Out of a Cake?

London Fashion Week's most star-studded party wasn't even an official part of fashion week. It was the birthday celebration by Ciroc for Mert Alas, one half of the celebrated photography duo Mert and Marcus. Mert's guest list included supermodel Naomi Campbell and actress Lupita Nyong'o (fresh from the BAFTA red carpet) along with the great and good of the fashion world, including British Vogue editor Edward Enninful and Victoria's Secret angel Doutzen Kroes. The group got a big surprise when they gathered round a giant birthday cake: Kate Moss popped out! The model and style icon managed to make climbing out of the cake look glamorous despite sporting a beaded maxi dress and proceeded to perch on the side and grab a microphone to pay tribute to the birthday boy. Take a look at her surprise starring moment ahead, along with some more shots from the glamorous party.
