"I couldn't be happier that Demi wants to come back this year," Cowell said in a statement. "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!"
Britney Spears and L.A. Reid won't be returning to the singing contest next season. No word yet on other judges. Reid lasted two seasons on "The X Factor." Spears and Lovato were replacements for Paula Abdul and Nicole Scherzinger, who lasted just the first season.
Lovato issued this statement: "I am so excited to return as a judge and mentor on 'The X Factor.' 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!"
Fox and Cowell would like better ratings. "The X Factor" has never been the fall hit that they hoped for, and the show may have hurt viewership for "American Idol."
