If anyone thought Britney Spears might be the nicest person on the "X Factor" judges' panel, then they might want to think again.

In a new 17-second promo for the show, Spears shows off she's got quite a lot of critical bad-girl sass lurking deep down inside that sweet Southern demeanor. Some of her choice quips from the super-short teaser, posted on the Los Angeles Times website, include:

"You can't destroy that song, sweetie,"
"Very predictable" "Bad to the bone,"
"You definitely don't have the 'X Factor.' "


Now that the audition process is over, the next step for Spears and her "X Factor" judges is boot camp."Wow can't believe @TheXFactorUSA auditions are over," Spears tweeted on Tuesday. "So much FUN... bring on boot camp!"

Fans won't get to see what other criticisms Spears shares with the show's hopefuls until the "X Factor" debuts on September 12.
