Demi Lovato and Simon Cowell confirmed Wednesday night that the second-year judge will not return next season, according to multiple published reports.
Fox had no comment.
Lovato's departure would mean another shakeup for the struggling X Factor, which has seen a revolving door of judges through its first three seasons. The series has seen its ratings drop every season and has not been renewed for a fourth season by Fox.
X Factor airs its season finale Thursday night at 8 p.m.
