The 'Criminal' singer tells one contestant she "can't destroy" a particular song in the latest clip.
Britney Spears can be seen delivering a series of critical comments to contestants on The X Factor USA in a new trailer for the upcoming series of the music reality show.
The promo asks if America's sweetheart has been spending to much time with music mogul Simon Cowell before she starts delivering her judgments.
"You can't destroy that song sweetie," she says to one hopeful before adding another was "bad to the bone".
Simon even looks over with a shocked expression at one point as the '…Baby One More Time' puts it bluntly to one contestant: "You don't have The X Factor!"
The singer signed up earlier this year alongside Demi Lovato to replace axed judge's Paula Abdul and Nicole Scherzinger.

Meanwhile, the singer's appointment has not come without controversy as some feared her reported unpredictable behavior.
The star has also been seen walking out of auditions and UK judge Tulisa called the star a "risky choice".
The X Factor USA will premiere in America next month.
