Fans are known to scream at Justin Bieber concerts, but barring all motivation to the contrary, fans are not supposed to throw things at the stage. 

That's exactly what happened to the pop prince at a concert Friday night in Atlantic City, NJ. A fan thought it would be clever to fling a hat over to Justin—ostensibly so the "Sorry" singer could wear it—but Biebs wasn't terribly keen on promoting that person's budding clothing brand. After Justin threw the hat back into the crowd, he took to skewering the audience member for ruining the moment. Several fan shot videos tell the tale, including this one below, in which Biebs implores all Beliebers to withhold their gifts. 

"Sorry, that was mean," Bieber said after scolding the interloper, who was probably blushing hard. He then justified his actions further, telling everyone that the hat-flinger almost tarnished the whole damn evening: 

The whole thing caused the young Bieber to lose his flow. "But yeah, no I lost what I was going to say," he said. "I was deep into, like, a mode and a zone. I was—I was into it. Now I'm out of it. I'll get it back. Just give me a second," he said while scratching his head. 

E! News points out that the singer's Purpose World Tour is getting ready for an international run of dates, which include stops in Japan and Iceland. Fans better keep their hats to themselves.
