Justin Bieber Flips Out At Super Bowl Maxim Party

Justin Bieber put his finger to bad use last night at a Super Bowl party filled with models and other hot chicks.

Bieber slinked in the back door at around 2 AM at the Maxim party in NYC. 

Apparently his 5-hour interrogation by U.S. Customs officials at the airport Friday got him riled, because he had his people shine a bright light at anyone who tried snapping a pic of him inside the party.  And Bieber's bodyguards were pretty successful -- except with the guy who got this photo.

TMZ broke the story ... Bieber was flagged by Customs because of his 2 pending criminal cases ... including one for allegedly assaulting a limo driver.

No models were hurt in this shoot.
