Pop star Demi Lovato quit the high-profile Jonas Brothers tour to enter treatment for "emotional and physical issues," according to her rep. The 18-year-old Disney star was the opening act for the Jonas Brothers international tour.
"Demi Lovato left her tour early this weekend in order to seek medical treatment for for emotional and physical issues she has dealt with for some time," her spokeswoman said in a statement.
"Demi has decided to take personal responsibility for her actions and seek help. She is doing just that. Demi and her family ask that the media please respect their privacy during this difficult time. She regrets not being able to finish her tour, but is looking forward to getting back to work in the near future."
Lovato rose to fame on The Disney Channel with her show, "Sonny with a Chance" and the movies "Camp Rock" and "Camp Rock 2," also starring The Jonas Brothers.
Lovato also shut down her Twitter page over the weekend, leading fans to tweet "#demicomeback." A source told TMZ that Lovato was in a "physical altercation with a female member of her tour recently." TMZ also states she is not in treatment for drug use.
The Jonas Brothers and Demi Lovato were scheduled to play in Little Rock September 30, 2010, but cancelled "due to changes in the worldwide tour schedule," upsetting many area fans.
