JUSTIN BIEBER scolded a fan in front of thousands of people for messing up THE MOMENT.

Bieber was performing in Atlantic City, when some fan tossed a hat onstage while he was talking in-between songs.

It apparently threw Biber off his game so he embarrassed the poor fan.


Bieber said, quote, “Take this moment to listen…and try not to give me a hat or whatever you’re trying to throw onto the stage right now, because I probably don’t want that [crap].”

The crowd cheered, and Justin said, quote, “Sorry that was mean. But…I lost what I was going to say.  I was deep into, like, a mode and a zone. I was…I was in it. Now I’m out of it. I’ll get it back. Just give me a second.”

A little while later, he apologized again, and got the show back on track.

Quote, “Sorry for throwing your hat, but you ruined the moment.  Whatever, let’s do it.”
