JUSTIN BIEBER was being chased in his Ferrari by a paparazzi scumbag. So he STOPPED DEAD IN TRAFFIC.

That didn't get the guy to leave him alone. He just sat there in the lane next to Justin, filming him.

And the guy on the other side of Justin stopped too, to record the scene with his phone.

With all the cars behind them beeping away, Justin finally sped off after some dude with a mullet came up and started complaining.
