Dionne Bromfield will perform at the Look fashion show during London Fashion Week, where Sarah Harding will make her catwalk debut.
Amy Winehouse's goddaughter - who is the face of streetwear brand Gio Gio - will take to the stage for a special musical performance at Westfield, Stratford City in East London on 17 September during the event, which will be opened and closed by Girls Aloud star Sarah.
The fashion show aims to celebrate high street fashion with brands including Miss Selfridge, Urban Outfitters, Next, Monsoon, New Look, River Island, Oasis and Dorothy Perkins set to showcase their latest collections.
Ali Hall, Editor of Look, said: "The Look Show has become an established part of London Fashion Week and readers absolutely love it. We're thrilled to be working with Westfield to make this season's show bigger and better than ever, and to be part of such an exciting retail launch."
Although Sarah will make her catwalk debut at the show, she has previously posed for lingerie company Ultimo and claims she keeps her fantastic figure by dancing.
She said: "I love to dance. I'm very energetic. In fact, I'm actually quite health-conscious. I've got a fast metabolism, but I go to the gym, too. At the moment I'm doing loads of work on the pull-up bar and I go walking a lot as well."
