The Blind Date presenter sashayed down the catwalk dressed in an Yves St Laurent top hat, shirt and tails as part of a glamorous Cabaret-style outfit.

The singer closed the charity fund-raising show at last night's Natural History Museum, which is now in its third year. Others modelling included Campbell, Girls Aloud singer Cheryl Cole, model Erin O'Connor, a reluctant Tracey Emin, rock daughters Kimberley Stewart and Lizzie Jagger and girl group the Sugababes. Sugababe Heidi Range lost one of her heels during her run on the catwalk but quickly recovered her poise. Olympic gold medallists Rebecca Adlington and Sarah Ayton and also took to the runway, complete with medals. The 2008 Fashion For Relief show was held in aid of the White Ribbon Alliance, which is supported by Mrs Brown. She opened the show with a speech about the charity, which campaigns for better care for women in childbirth in the Third World, dressed in a bright red dress and a pair of high heels. "Every minute around the world a woman dies in pregnancy, this hasn't changed in 20 years," she said. "The world is coming together to put an end to the shameful and needless deaths." Organisers were hoping to emulate the success of last year's Fashion For Relief show, which raised more than £1 million for the Rotary Club Flood and Disaster appeal.
