NEW YORK (CBS) Disney star Demi Lovato has dropped out of her tour with the Jonas Brothers to enter a treatment facility, her rep confirmed on Monday.
Lovato checked in over the weekend to seek help for "emotional and physical issues."
In a statement to TMZ, her rep said, "Demi Lovato left her tour early this weekend in order to seek medical treatment for emotional and physical issues she has dealt with for some time."
"Demi has decided to take personal responsibility for her actions and seek help," the statement continued. "She is doing just that."
Her rep concluded, "[Demi] regrets not being able to finish her tour, but is looking forward to getting back to work in the near future."
The reason for the treatment was not specified. However, a source close to the Lovato family told People magazine, "She was bullied in school. She fought through eating disorders and has struggled with cutting...Demi is taking control by getting help."
Sources close to Lovato told TMZ that the singer was in a physical altercation with a female member of her tour recently, and the incident was a "catalyst" in her decision to seek professional help.
