Demi Lovato has entered a treatment center, her rep confirmed to MTV News on Monday (November 1). The singer/actress has left her current tour with the Jonas Brothers to seek treatment.

"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," her rep said in a statement. "Demi has decided to take personal responsibility for her actions and seek help. She is doing just that."

Lovato is currently in South America on the "Camp Rock" Tour with the JoBros. "[Demi] regrets not being able to finish her tour, but is looking forward to getting back to work in the near future," the statement continued.

According to TMZ, Lovato recently got into a physical altercation with a female on tour with her; that report was not confirmed by Lovato's rep.

On Saturday, the JoBros announced that they couldn't have a Web chat with their fans, tweeting, "Due to tour production issues that require our attention, we won't be able to do the webchat on Cambio today. We can't wait to talk to all our fans again.We love you." It is unclear whether the "tour production issues" were related to Lovato's exit.

Lovato also unexpectedly shut down her Twitter page over the weekend. Soon after, the hashtag #demicomeback was a Twitter trend, according to CNN.
