Aussie X Factor judge Kate Ceberano is said to be on the verge of quitting the troubled show.

According to Sydney's Daily Telegraph, Cerberano is threatening to walk out on the series and her only remaining contestant, Vince Harder.

On Monday night's show, she was forced to eliminate one of her own contestants from the game - apparently claiming afterwards that the votes had been rigged.

She has also been locked in a bitter on-air feud with fellow judge Mark Holden throughout the series.

Fortunately, if Ceberano decides to quit, not many will notice: The X Factor has bombed in the ratings for Aussie network Ten and a second season has already been ruled out.
