The famous singer, Justin Bieber, was strolling around Amsterdam like a “common man” because he was not in a mood to be recognized and crowded with fans. He put on a stick-on goatee and a weird brown wig and thought people won’t recognize him. Well, better luck next time, Bieber.
Most of the people on the street recognized him and started making his videos but he had his security behind him and they stopped them. This is the reason which certainly didn’t help him to blend in with the crowd.
