Demi Lovato
The drama has prompted Disney executives to reconsider the future of the show amid allegations from Lovato's father that she was exhausted and overworked.
A Disney representative tells TMZ.com, "The health and well-being of Demi comes first and if we have to make other plans, we will."
Specific details about Lovato's decision to seek treatment for her troubles have yet to be revealed.
Plans for a second season of the TV programme were put on hold in July (10) to allow Lovato to hit the road with the Jonas Brothers, and production on the new series was due to resume in January (11).
