Many of the world's most successful entertainers - Billy Joel, Elton John, Phil Collins, Duran Duran - have been swindled by their managers. Now former Black Sabbath rocker Ozzy Osbourne has claimed he's still wary of the "true motivations" of the business dealings of his wife, Sharon. "When she talks to me about something, I have to work at whether she's talking to me as a loving wife or a f**king scumbag manager," Osbourne said. "I'm not very good at understanding these f**king contracts. I have to let someone do it for me, and if someone's going to rip me off, I'd rather my wife do it than someone else."
