First Cheryl Cole was booted from the U.S. version of Simon Cowell's 'The X Factor,' then the UK version -- but now the singer and reality judge is rumored to be applying for a U.S. visa as her employment drama continues.

According to The Hollywood Reporter, the British pop star is currently in a "chess match" with 'X Factor' producer Fremantle.

The report says Fremantle is trying to avoid paying Cole for her four days of work as an 'X Factor' judge, but they don't want to breach her contract.

"They don't want to pay her," a source told THR. "It's a chess match."
