The series officially ended on January 2, 2011, after the 2nd season, after Lovato completed treatment and left her role.
Demi Lovato left the show after season 2 for mental health reasons. As a result, the show was renamed "So Random!" and focused only on the sketches, rather than the behind-the-scenes antics.
This was the second Disney Channel original series in which the lead actor/actress left during its run, and the fourth Disney Channel series to have a main cast member leave during its run.
