His Bieber fever could not be contained.

Justin Bieber is on a world tour right now. At a concert the other night a fan rushed the stage and attempted to touch the pop star. Well security tackled the fan, in the process also forcing a piano to flip over.

From what I could tell Justin was not hurt in the process. So Belieber's everywhere you can stop holding your breath. It was amazing how Justin was able to keep singing through that whole ordeal.
