Celebrity royalty joined Belvedere Vodka to celebrate the launch of Born This Way at an intimate performance from Lady Gaga. London's A-List including Kate Moss, Florence Welch, Erin O'Connor and Will.I.Am filled the exclusive Annabel's club to watch Gaga perform.

The stripped back acoustic performance at William and Harry's favorite London hangout wowed the select audience of 150 people. Gaga arrived in a green veil and a leopard two-piece bikini with black print, before performing four songs, including Born This Way, album classics Speechless and You.

Gaga dedicated Speechless to her close friend Elton John, who she wished could have been there, she described him to the audience as 'free from the artifice of the industry'. Born This Way, she used as a shout out for supermodel Kate Moss, describing her as 'born perfect'.

Guests drank Belvedere cocktails inspired by the first three singles from the album - Born This Way, Judas and Edge of Glory.
