The countdown is almost over! Tonight, a batch of fresh, new talent will take the stand and two of Hollywood's biggest pop stars will sit behind the judge's table for the first episode of "X Factor" USA Season 2.

It seems that the entire Internet has been abuzz with anticipation about tonight's premiere -- and rightfully so, with the show's panel of A-list judges and a track record for churning out mega-stars like One Direction and Leona Lewis.

This year's competition promises to be bigger and better than ever before. Judges Demi Lovato (aka #QueenD) and Britney Spears have been tweeting up a storm about the big premiere -- and we're getting pretty excited.

  • One Direction

    Before they were international superstars, the five boys of One Direction were just hopeful singers auditioning for a reality show. After they were put together into a band by Simon Cowell, the guys were on the fast track to pop stardom.

  • Little Mix

    Equally loved and hated by Directioners (singer Perry Edwards is dating Zayn Malik), Little Mix won "X Factor" the year after One Direction. The four girls, who originally auditioned separately, became the first band to win the competition. <em>Correction: A previous version of this article stated that Little Mix won 'X Factor' the season before One Direction. In fact, it was the season after. The story has been updated. </em>

  • Joe McElderry

    21-year-old Joe McElderry claimed the winning slot on the sixth season of "X-Factor" with his <em>Glee</em>-worthy performance of "Don't Stop Believin'". Do you think this young performer belongs at McKinley High?

  • Leona Lewis

    The most famous "X Factor" finalist prior to One Direction, Leona Lewis has gone on to win Grammy awards and top the US charts with her unique brand of R&B-infused pop.

  • Leon Jackson

    23-year-old Scottish singer Leon Jackson won over the hearts of the judges and the audience with his Frank Sinatra voice and Green Day style.
