Disney star Demi shows you're never too young for rehab...
Disney Channel teen star Demi Lovato has finished a three-month stay in rehab but has not yet decided when or whether to return work on her Sonny With a Chance TV show.
A source close to Lovato (18) said the singer and actress returned to Los Angeles earlier this week.
Back in November, she had pulled out of a concert tour and entered a rehab facility to get treatment for what were described as "emotional and physical issues".
Lovato had fought to overcome eating disorders and was bullied at school in the past, her spokeswoman said at the time.
The future of her TV show Sonny With A Chance, in which Lovato plays the role of a comedy actress, was still unclear.
For now she "will continue to focus first and foremost on her well-being," the source said.
A Disney Channel spokeswoman said that "Demi's management will inform us when she is able to return to work".
In Lovato's absence, writers on Sonny With A Chance have been working on sketches for So Random -- a show within a show on Sonny. Disney Channel said that So Random was being developed as a full series and production started earlier this week.
Lovato got her break as the star of the 2008 Disney Channel movie Camp Rock and has since released two hit albums. She dated teen heart-throb Joe Jonas in 2010, and was on a Latin American tour with the Jonas Brothers before abruptly pulling out in November 2010.
