A new report claims that JUSTIN BIEBER was, quote, "extremely abusive" to the crew of a private plane on Friday . . . just ONE DAY before he was supposedly looking for a pool in New York City to have himself baptized in.

 

This time, it isn't tabloid silliness . . . there's an actual POLICE REPORT.

 

It says the captain warned Justin and his friends on "several occasions to stop smoking marijuana."  Apparently, it got so bad that the pilots had to wear OXYGEN MASKS to avoid getting high off the smoke in the air.

 

The captain ALSO had to warn Justin's group to, quote, "stop their harassing behavior toward the flight attendant."  The woman told authorities that Justin and his father were, quote, "extremely abusive verbally."

 

Yup, Justin's "cool dadJeremy Bieber was one of the partiers on the plane.

 

To be clear, the "abuse" was not physical or sexual in nature, and the crew is not pressing charges against Justin.  However, the flight attendant says she will NEVER work another flight with Justin and / or his dad.
