Pop group Girls Aloud, looking as glamorous as ever, were the talk of the town when they stepped out together recently at a London Fashion Week event in Mayfair. Bandmates Kimberley Walsh, Nadine Coyle, Nicola Roberts and Cheryl – who last November revealed they are to reunite for an arena tour this year in memory of their late bandmate, Sarah Harding – stole the show as they attended the Perfect Magazine and AMI Paris Party. But the band member who turned most heads was former X Factor judge Cheryl, 40, as she debuted a new look – her hair in a high bun with a choppy fringe – and not a wrinkle in sight.
