Lady Gaga celebrated the arrival of her new album Artpop by staging a star-studded gig in London on Friday (06Dec13). The Poker Face singer took over London nightclub Annabel's for a very special live show, and she entertained a crowd full of celebrities from the world of film and music with tracks from the album, which was released last month (Nov13). The exclusive audience included award-winning singer Adele, pop star Jessie J, Sting, James Blunt, Les Miserables' Eddie Redmayne, Bryan Ferry, Emile Sande, and Harry Potter actress Emma Watson. Gaga addressed the wealthy crowd by jokingly asking for donations, saying, "Hello, rich people. You should be happy. I'll be passing around a hat as I'm extremely poor. If you could contribute to my art, that would be great. I need some more feathers for my hat." British supermodel Naomi Campbell, who was due to attend the event, skipped the party saying she was "in mourning for Mandela" following the South African leader's death on Thursday (05Dec13).
