Demi Lovato is going from X to ex…

The 21-year-old part-Mexican American actress has decided to vacate her seat at the judges table on Fox’s The X Factor at the end of the third season.

Lovato, who has served as a judge and mentor on the singing competition for two seasons, plans to focus the next year on her music. Lovato released a new album, Demi, in March and is headlining her first arena tour beginning in February.

“I think ultimately my main thing is singing,” she told People magazine last month. “Maybe movies once in a while, if the right role comes along.”

Speaking on the red carpet after Wednesday’s performance finale, X Factor boss Simon Cowell confirmed Lovato’s exit, but indicated the door will be left open for her in the future.
