For days, we've been curious to know what exactly happened that made
Demi Lovato snap before she was urged to go to rehab. According to
People magazine, it all started when the singer had a night off from her tour with the
Jonas Brothers. The next day, Demi got into some trouble after tour managers and her stepfather
Eddie De La Garza found out that she and a group of others may have been partying too hard.
"When tour management found out about this, they talked to the people involved, including Demi," the
source said. "Demi reacted badly and perceived that someone on tour had told on her."
The
Camp Rock 2 star thought one of the dancers on tour was the tattletale, and got in this person's face on the airplane that day. The source noted that there was a "short, physical altercation," but that it was "one-sided."
The report also emphasized that — despite rumors to the contrary —
Joe Jonas and his girlfriend
Ashley Greene were definitely NOT involved in any incident with Demi whatsoever.
