Demi Lovato, one of Disney's biggest names, checked herself into a treatment center for "emotional and physical issues she has dealt with for some time," the Hollywood gossip website TMZ reports. Lovato's representatives have confirmed the news.
"Demi has decided to take personal responsibility for her actions and seek help," a rep confirmed to People. "Demi and her family ask that the media please respect their privacy during this difficult time."
Her father, Patrick Lovato, told RadarOnline that the stress of working in showbiz got to her.
"There are a lot of pressures. That is one of the things I worried about when she signed with Disney," he said. "It's just going to happen."
Numerous outlets are saying that her issues stem from bullying, a problem the 18-year-old has dealt with since the seventh grade. She dropped out of middle school for homeschooling, she told Ellen DeGeneres in 2008. There have also been rampant rumors of cutting, eating disorders and other self-abuse, but not drug use.
"She needed help before a smaller problem got worse," a source tells Us. "She is doing okay. She has been forced into showbiz from a young age and that puts tremendous pressure on someone … everyone is really happy she is getting help."
Lovato, who is star of Disney's Camp Rock movies and the sitcom Sonny With a Chance, was on an international tour as a special guest of the Jonas Brothers, but left the tour over the weekend to enter an undisclosed facility, according to her reps.
Lovato was linked earlier this year to Joe Jonas, her Camp Rock co-star, but the two broke up and said they remained friends.
