New Hilarious The X Factor Preview

New, never-before-seen clips of Britney and the rest of the judging panel on The X Factor debuted on today.

One contestant sang an awful rendition of “Circus,” and Britney’s face is priceless! She covers her ears and shakes her head.

Another contestant slammed Demi for using auto-tune, and Brit asks: “I wanna know who let you on stage.”

Check all that out and more:

The X Factor debuts during a two-night premiere September 12-13 at 8 p.m. on FOX.


And this is only the beginning…
