LOS ANGELES, March 28 (UPI) -- Fox says Demi Lovato has signed on as a judge for a second season of the American talent show "The X Factor."
"I couldn't be happier that Demi wants to come back this year," judge and producer Simon Cowell said in a statement to EW.com Thursday. "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."
