Looks like Britney Spears's judging stint on the "X Factor" is a one-and-done sort of thing. Us Weekly is reporting that the singer will be fired from the show, after only one season on the judging panel. "Britney will get the boot," a source told the magazine. "Producers wanted her for the long haul, but it isn't working." L.A. Reid, who was a judge for the first two seasons of the show, will also be leaving. That leaves show creator Simon Cowell and Demi Lovato, who was hired this year alongside Spears.
