The Associated Press is reporting that Ozzy Osbourne sent his congratulations from Sydney, Australia on Britain's Prince Charles wedding plans.Charles' recent visit to Australia has been overshadowed by scrutiny of his coming marriage to Camilla Parker Bowles, which has fazed some observers because their romance began before the late Princess Diana died. Osbourne, rock and roll's self-proclaimed "Prince of Darkness," weighed in on the issue while in Australia's biggest city to host the first MTV Australia Video Music Awards, calling the prince a "mate" and saying he should be allowed to marry Parker Bowles in peace. "It's his business you know. His first wife got killed so what's he expected to do, be single for the rest of his life? If he likes her and she likes him or whatever, good luck on them," the BLACK SABBATH lead singer told reporters in Sydney.
