If fans of "The X Factor" are wondering just who will be the meanest judge this season, a new promo released by Fox has the answer: It's Britney, bitch!
In an "X Factor" first-look clip released by the network, Britney Spears  shoots down a vocalist with one cutting comment: "I don't know who let you on stage."
Not to be outdone, Simon Cowell  is seemingly back in rare form, cutting a contestant to the quick with one of his classic putdowns.
"You perform like a dog trying to lay an egg," he sneers in the promo.
The rest of the sneak peak, which repeats the mantra, "Are you ready?," is equally entertaining. Spears tells a singer that he's "hot," while Cowell delights in embarrassing fellow judge Demi Lovato  by divulging her dating status as "single." It also appears several would-be superstars end up in the emergency room (shades of "American Idol's" Season 11 mishaps, which included a vocalist plummeting off the stage as well as other medical drama in the audition stages).
In other "X Factor" news, the reality show crossover continues as reports are swirling that Tarralyn Ramsey, a rejected singer from "The Voice," wowed the judges in Greensboro, Ky. Additionally, Shelby Lynn Tweten, famously featured in the "American Idol" Aspen, Colo., auditions (she suffered from bipolar disorder) showed up in Kentucky for another shot.
"The X Factor" debuts at 8 p.m. Sept. 12 and 13 on Fox.
Below, watch a backstage interview with the judges that sheds some light about a contestant that was so awful, they had to vacate the set. Also, Lovato's asserts that she is no pushover in the judging department, either.
