First he knocked himself out, now Justin Bieber might be going deaf -- because a sea of teenage fans in Paris just unleashed the loudest, most high-pitched earsplitting screams we've ever heard ... and if you don't believe us it's all on tape.
It happened moments ago in the City of Love -- Justin appeared on a balcony, where a hormone-fueled throng of adoring fans waited outside.
To say the crowd erupted is a gross understatement -- their endless shrieking nearly blew out the microphone in the camera. (In fact, you may want to turn down your speakers before watching.)
Bieber waved, blew kisses, sang a few verses of "Boyfriend" ... then bade his farewell, saying, "Je t'aime beaucoup!" (That's French for "I'm filthy rich.")
There wasn't a dry pair of panties eye in the house.
