Music mogul TONY WILSON has launched a blistering attack on pop star Morrissey, calling him a nasty human being. Wilson, who managed New Order and Happy Mondays, is not happy at the former The Smiths frontman's diva demands and believes it's about time his fans know the truth. He says, "Steven (Morrissey) is a nasty human being. He treats people like s**t and has done throughout his career. Smith fans confuse the art with the artist." Recently, Canadian rockers The Dears slammed Morrissey for behaving like a diva on their recent US tour together.
