Expect more playful squabbling between Demi Lovato and Simon Cowell on "The X Factor" this fall!

FOX has announced that the 20-year-old pop star will resume her job as a judge and mentor -- to finalists who make it into the Young Adults group -- on the third season. This will mark her second one. She made her debut last fall along with fellow new judge Britney Spears, who announced in January that she would not return to the series.

Lovato, the show's youngest judge, said in FOX's statement she is "so excited" to come back to "The X Factor, adding: "Last season was an unbelievable experience and I really enjoyed developing personal relationships with the contestants and the panel. I look forward to taking my previous experience and applying it to make this season even better!"

Cowell, who often sparred with Lovato on the show over opinions about contestants, said: "I couldn't be happier that Demi wants to come back this year. She's a superstar in her own right and was a fantastic mentor last year. Even though she can be really, really annoying -- I truly enjoyed working with her and so did the artists. I'm especially pleased she's back, even during her world tour!"

In addition to Spears, L.A. Reid, who had served on the judges' panel for the first two seasons, is also not returning for season 3. Auditions are being held over the next couple of months in New Orleans, Long Island, New York and Denver.
