Actress Nicole Kidman is modelling at London Fashion Week on Thursday (20Sep07) - but only virtually. The Australian Oscar-winner will make her catwalk foray on the big screen rather than the runway. Kidman, 40, stars in a film made by Antoni Burakowski and Alison Roberts to mark the 20th anniversary of their label, Antoni + Alison. She will model the duo's spring collection in a 10-minute short, which takes the place of their fashion show. Industry sources say Kidman - who usually commands hundreds of thousands of dollars for a film - volunteered her services as an anniversary present to the couple.
