Plague hits camp Disney!

Okay, maybe not the plague, and maybe not even an illness but Demi Lovato joined Selena Gomez is in Team Lets-Cancel-all-our-shows last night.. but why?  No-one official is offering an explanation as to why she cannot perform which is a bit fishy to me! But its worrying too as Demi is about to embark on a intense summer tour with EX Joe Jonas & Co. She did attend the meet and greet before the show where she was helped to her seat. As well as this several of her 
tweets (that were later deleted from her twitter page) were more than odd! A close friend of hers has recently died which may have something to do with it, as well as her over exercising and training for tour. Poor demi! I think there is whey more going on between the lines, but all the facts suggest she is not a happy bunny! Get better soon Demi whatever it is that's wrong!!!
