Wowser. Last night at hip New York cabaret hotspot The Box, anyone who was anyone danced the night away while sipping on champagne and chomping down miniature fish and chips in cones. With Kate Moss looking on in a white satin jacket and sequinned dress, UK star Adele officially opened the proceedings, and was quickly followed by super-cool performer La Roux amongst others. Then there was Simon Cowell, who stood front row checking out the talent while real-life Gossip Girl couple Penn Badgely and Blake Lively mingled with J-Lo and Sir Phillip Green. By 2am the party was still in full swing and the evenings entertainment was rounded off with Kevin Spacey taking the stage for an impromptu recession-tastic rendition of 'I aint got no money' managing to get the entire venue to join in on the chorus ! Even Simon Cowell joined in ! It was the perfect end to a week of celebrations that showed how much NY eagerly anticipated the fashion megastores arrival. Follow our Twitter feed of the evening here!
