Report: Demi Lovato Leaving The X Factor

Another X Factor shakeup is underway.

Demi Lovato, who has served as a judge on the Fox singing competition for the past two seasons, has tendered her resignation, reports People.com.

“She plans to spend next year completely focused on her music,” a source close to the singer-actress told the site. “She had a great run and a good time.”

A Fox spokesperson declined to comment.

Of course, it’s not clear if The X Factor — which has seen its ratings plummet to scary new lows this fall — will live to see a Season 4. For his part, exec producer and star Simon Cowell predicted to reporters earlier this week that, “The show will be back next season,” although he hinted at a possible new role for himself.

“[It’s] got to be more different next year than it was this year,” he added.  “[I’m in] the middle of a presentation of what we think the show should look like and what the fans would like. And yes, my role could change.”
