British pop star Lily Allen has slammed supermodel Kate Moss for being an "irresponsible role model". The SMILE singer is set to launch a clothing range for British fashion chain New Look, and will go head to head with Moss' collection for rival retailer Topshop. Allen believes her range for New Look promotes positive body images - and blames Topshop tycoon SIR PHILIP GREEN for fuelling the Moss "madness", by paying for the svelte star's fashion expertise. She says, "I like what New Look are doing and I like what they are about. "They have responsible role models like me and Drew Barrymore and they're very conscious of having positive body images and promoting positive women. "Unlike KATE MOSS and that f**king billionaire who's thrown a load of money at her so we get to see what he wardrobe is like. It's madness."
