A representative says in a statement that Disney star Demi Lovato has entered a treatment center to deal with "emotional and physical issues."
The statement did not specify the 18-year-old's problems.
A person familiar with the situation previously told The Associated Press that Lovato entered treatment for problems including an eating disorder and cutting herself. The person, speaking on condition of anonymity because they were not authorized to speak publicly due to the sensitivity of the matter, later clarified the statement, saying Lovato had dealt with those issues in the past.
The statement by Lovato's reps did not say where the "Camp Rock" and "Sonny With a Chance" star was being treated.
Lovato had been on an international tour with the Jonas Brothers. However, she left the tour over the weekend.
The statement said Lovato was taking "personal responsibility for her actions."
