DOUBLE TROUBLE: Collaborations were a running theme at Alexander McQueen’s show on Friday night. Prima ballerina Sylvie Guillem said she would be performing in a contemporary production of “Eonnagata” at Sadler’s Wells in London. “McQueen has designed the costumes and I have been working with the choreographer Robert Lepage and Russell Maliphant,” she said. Elsewhere, Naomi Campbell and Farida Khelfa were chatting away – perhaps discussing their latest film venture. “I have just finished French film ‘Barbe Bleu’ or ‘Blue Beard’ with director Catherine Breillat and will start filming ‘Bad Love’ with Naomi Campbell next year,” said Khelfa.
