Worried mum Britney Spears has ordered husband Kevin Federline to get rid of his pet sharks, fearing one of his kids could be maimed by the flesh-eating fish. The pregnant pop star has never been a fan of her husband's six Australian grey nurse sharks and now she wants them out of her house. A source tells American publication Life + Style, "Kevin loves those sharks; he even named them. But Brit said there's no way he'd be keeping them."
