Keep your hands to yourself, especially if you’re dealing with Justin Bieber.

Heading to his show last night in Barcelona, Justin “Danger” Beiber was driving through a crowd of fans. He wished them well as drove through, allowing them a glimpse at his royal Biebness. But his trust was quickly taken advantage of. A crazed fan, probably drunk on the power one receives when they lock eyes with Bieber, broke the seal and reached into Bieber’s limo aka the Bieb-mobile aka the Bieber Express aka Derek the Limo. What’s Bieber to do? The only thing an international man of mystery can: Punch him in the face.

That’s right, Bieber gave the fan the old one-two salute right in the jaw, and the fan was left bloodied on the street as Bieber drove away. Put some ice on those knucks, Bieber. You live to fight another day.

Bieber's fans quickly came to his aide:
