K-Fed's call to cops: 'Britney's got a gun':
Our source said: "Jamie's new-found publicity enraged jealous Britney. And after calling Kevin that night she rang Jamie and told her, 'You're not going to be the only f***ing Spears on the front cover of a magazine next week!' and then hung up." Meanwhile Britney lost it when Kevin's lawyer Mark Kaplan showed up at the house and tried to talk her round.
