Demi Lovato Still 'Doesn't Think She Needs Rehab' After Checking Into Treatment

Demi Lovato checked into a treatment facility outside of L.A. on Aug. 4, but RadarOnline.com has exclusively learned she already wants out!

"Demi doesn't think she really needs rehab," revealed a source close to the 25-year-old "Sober" singer.

"Honestly, she believes she can get sober without it and that it is just a bit extreme," said the source, "but she is going to comply with her family and friends'  wishes to complete the program so she can avoid drama."

As RadarOnline.com reported, Lovato overdosed on July 25 following a night of hardcore partying with pals — just several weeks after admitting to the world that she relapsed after almost six years of continuous sobriety.

However, according to the source, Lovato isn't the beacon of hope she once was.

"Demi just doesn't seem to be taking this sobriety thing as serious as she did the first time around and no one understands why," the source revealed.

And although the location of her rehab is currently under wraps, RadarOnline.com has learned Lovato's treatment program will cover all the bases.

"She is at a place where they treat multiple diagnoses," the source noted. "In Demi's case, she suffers from alcoholism and addiction, as well as mental disorders and eating disorders, all of which she has talked about for years."

Added the source: "She is just really starting off at square one right now."
