Demi Lovato, Sonny With a Chance
In 2010, Demi Lovato was at the height of her Disney fame. She was dating a Jonas brother, had a successful music career, and starred as Sonny in the squeaky-clean Disney comedy Sonny With a Chance. Then, in November of that year, the starlet checked into treatment for “emotional and physical issues,” including both an eating disorder and drug use.
Demi did not return for the show’s third season, and that meant that Sonny With a Chance needed some serious reworking. With its title star out of the picture, the show was reworked as a Sonny-free sketch comedy show called So Random!, and retained all its other characters. So Random! lasted for one season before Disney cancelled it.
Since being dropped by Disney, Demi has continued to have a successful music career. She’s also set to return for her second season as a judge on FOX’s The X Factor.
Show Survived: Sort of.
Actor Returned: No.
