Kelly Osbourne has rubbished rumours she married her rocker boyfriend at a music festival in Ireland yesterday (03SEP06). The rock heiress was reported to have wed MATTY DERHAM, the bassist from little-known band Fields, on a bouncy castle church at the Electric Picnic Music Festival in County Laois. As the rumours circulated Osbourne's parents SHARON and Black Sabbath frontman Ozzy were said to be furious. But the 21-year-old insists the story is "totally untrue". Her spokesman GARY FARROW says, "Over the weekend a number of rumours circulated very quickly suggesting that Kelly Osbourne had got married at a festival in Ireland. "This is totally untrue and is as real as the inflatable church that carries out these non-legally binding mock marriages for fun."
