The Internet lit up this fall with tales of Demi Lovato falling off the Jonas Brothers tour to head into a rehab-of-sorts. But what happened? Initial speculation points to a fight Demi had with a female dancer on the tour. Word has it that after tales of a night of "partying" got out, Lovato placed the blame of whistle-blowing on a dancer. That, in turn, allegedly led to fisticuffs which left the dancer a little beaten and Lovato a little shaken (aww, poor girl), and she decided that she needed to get help. She settled her differences with dancer Alex Welch in December.
