Demi Lovato was singing Solo at her concert and then she throws a knife at Joe! No, just kidding but she did it verbally. Remember that line when she says "You sing to me, too bad you couldn't even stay on key. If your life is such a mystery why don't you stick to the tambourine" Instead of "Why don't you just stick to acting" Of course she has to be bitter because he told everyone He broke up with Her. It's just does she really want to cause drama right now? Right before their tour together? This, kids, is the reason why you don't date your co-stars, band mates, and best friends.
