"Boring" is a word rarely associated with Britney Spears, but that's exactly how she's being described by producers of 'X Factor.' A new report says co-creator Simon Cowell is leading the charge to fire Spears before next season because she just wasn't entertaining enough on the show.

Us Magazine quotes multiple sources who says the 'Till the World Ends' performer won't be back. "Britney will get the boot," an insider claims. "Producers wanted her for the long haul, but it isn't working." A second insider says Spears didn't earn her $15 million salary. "They paid all that for her to say 'amazing' and offer half-claps," the source said.

Another source gets at the real reason the Brit experiment didn't work out: "(Simon) wanted crazy Britney, but he got boring Britney." Hey, if Simon wanted crazy and unpredictable on the judging panel, why didn't he stick with Paula Abdul?

In October, Cowell had called Spears "a very, very good judge." She guided her protege, 13-year-old Carly Rose Sonenclar, to a second-place performance this season, behind winner Tate Stevens. If Brit gets the axe, at least half the 'X Factor' panel will need to be replaced, because fellow judge L.A. Reid is also leaving the show. No word on the fate of Demi Lovato, who said she has "no idea" whether she'll be invited back.

If the potential loss of her job isn't bad enough, Brit's personal life might be falling apart as well. Rumors have been swirling that Spears and fiance Jason Trawick are fighting a lot these days. "They are pulling away from each other. Unless things change, they will split for good," a source told the magazine.

Yikes. Someone give Britney a hug!
