Another thing that makes it hard to feel any sympathy for him too is because he is really immature at times... I mean the whole baby daddy accusation incident has BEEN over for months now: we all knew he wasn't the father of that girl's baby, and even the baby daddy himself (who was in prison) came forward and confessed they concocted that story about Bieber being the daddy to get money off the scandal.
That was over and done with, but a short time later, he, for no reason, starts taunting her on Twitter over the matter... NOW, he's written a song poking fun at it... it's over kid, let it die already, you're making yourself out to be the lesser person in this situation by continually bringing it back up when it ain't necessary.
