THE SIMPLE LIFE star Nicole Richie is considering having plastic surgery to change the shape of her nose. The slender style icon despairs over her unsatisfactory feature, but she has already found her dream nostrils: model KIRSTY HUME's. She says, "If I could change anything about myself it would be my nose - I hate it. "I'd get a nose done like Kirsty Hume's; she has my kind of nose but smaller. "I see really good nose jobs in LA but it's a big decision."
