The night before she voluntarily entered treatment, Demi Lovato decided to head out for a little fun. That’s when trouble began. A source says:
"As she did on most nights off, Demi invited her band, dancers and her parents to dinner. Afterward, she broke off with a very small group."
The following morning, the group was questioned on whether or not they were out partying. The insider continues:
“When tour management found out about this, they talked to the people involved, including Demi. Demi reacted badly and perceived that someone on tour had told on her."
The Disney actress approached a dancer while flying on an airplane the same day. She thought she was the one who snitched:
“There was a short, physical altercation. Afterwards, Demi felt awful about her behavior and realized she needed to take personal responsibility for it. Because of this, and because of the battles Demi has fought throughout her life, both she and her family realized she needed to take steps to get help immediately."
The family source wants to stress that Demi is NOT in drug rehab.
