because these days it's easy to make Demi look bad, especially with these kind of stories.
Is it from AD again? *facepalm* they once made up such a story, then the guy who met her was really angry and said she was really sweet and nice and all.
Anyway, I don't believe these strories anymore, and i find it extremely annoying when people say they don't like her anymore because of that when none of them ever has met her...
rant over.
