TMZ Complaint Department - Attack of the Beliebers - Video

Credit: TMZ

When TMZ leaked the nude guitar pics of Justin Bieber, the gossip site may have unknowingly made a powerful (or, at the very least, a determined) enemy.

The TMZ newsroom was FLOODED with thousands of calls from angry Beliebers -- who all seemed to be upset about the story we posted featuring their hero in his birthday suit.

They yelled ... they screamed ... some cried ... (and that was just our staff).

But the Beliebers were fired up too -- so we assembled some of our best producers and put them on the phones to address the concerns.

The following video displays the mixed, confused, occasionally-hostile reactions of Beliebers. Check out "TMZ Complaint Dept. -- ATTACK OF THE BELIEBERS" below via TMZ:
