Demi Lovato will leave her judge's chair on The X Factor at the end of the current season, according to reports. Tonight is the first of a two-part finale for the third season of the talent show.

"She has a great time, but she's going to focus on her music next year," a source tells Us Weekly.

Lovato released her latest album, Demi in May, but hasn't toured in support of her recording yet.

The former Disney star judged the past two seasons of X Factor alongside Britney Spears, L.A. Reid, Kelly Rowland, Paulina Rubio and, her boss, Simon Cowell.
