Justin Bieber Decked a Fan in the Face in Barcelona

Justin Bieber Decked a Fan in the Face in Barcelona
Justin Bieber seemed to be mellowing out a bit in recent weeks, charming patrons at a random Toronto bar with an impromptu piano set, showing genuine appreciation for his fans onstage, and taking home a handful of American Music Awards. Unfortunately, it seems like the young Canadian pop talent is taking his PR team on another rollercoaster ride after an altercation in Barcelona.
 
He performed in the Spanish city last night (November 22), and as his limousine was moving through the streets a particularly enthusiastic fan approached the vehicle and reached through the open window. The Biebs responded with a swift fist to the dude's face, leaving the fan bleeding from the mouth.
 
Thanks to TMZ, you can see the whole thing on camera (then watch it a million more times in slow motion) down below.
 
It's not the first time this year that a public appearance has gone sour for Bieber. His recent show in Manchester, went especially poorly; after a couple of teens hurled hate speech at the city's mayor, Bieber stormed off the stage when fans wouldn't stop screaming long enough to hear him sing. Before that, he lashed out against screaming fans in other cities, as well.
