The revolving door continues to spin on Fox’s “The X Factor,” as rumors swirl that Britney Spears has quit her post as judge on the singing competition skein.

According to a report from TMZ, Spears is leaving the judges table to focus on her music career. Exec producer and fellow judge Simon Cowell was rumored to have been let down that Spears did not add much spark to the show and planned to show her the door.

The U.S. version of “X Factor” has only seen two seasons on Fox, but has tapped seven different people to judge the show since its incarnation. During the competition show’s fall run, Spears and Demi Lovato were added to the panel to attract a young demo after season-one judges Nicole Scherzinger, Paula Abdul and Cheryl Cole exited the skein.
