Justin Bieber did Floyd Mayweather proud, punching a guy in the face hard enough to make him bleed.
The Biebs was in Barcelona, driving to perform Tuesday night, when a guy ran up to the car and stuck his hand in the window to touch him. Bieber responded with a quick jab to the face.
The guy ended up a bloody mess as he and his friends reacted in shock.
But we think there was more to it and the guy was up to something else that resulted in Justin Bieber’s reaction.
