It started out like just another day in the world ruled by Justin Bieber. That is, until he showed up unannounced to a room full of his fans…

Hundreds of dancers gathered for their shot at a place on an upcoming tour. The only thing is that they didn’t know whose tour they were auditioning for and then, Justin Bieber walked into the studio, making everybody's jaws drop.

As you can image, Twitter lit up like a nuclear warhead doused in gasoline.

Justin Bieber is walking toward me right now!!!
