The Smashing Pumpkins sued former manager Sharon Osbourne Tuesday in California court, alleging fraud, breach of contract and other charges. Osbourne, wife and manager of heavy-metal singer Ozzy Osbourne, quit her post last month, seven weeks before the release of the band's MACHINA/the machines of God (Feb. 29). At the time, she said in a statement that Pumpkins leader Billy Corgan was "making [her] sick." "This timing portrays a calculated, vindictive attempt to damage the group both emotionally and professionally," the Pumpkins said in their lawsuit. A representative for Osbourne said Wednesday he had not seen the filing and could not comment.
