Word of caution to Justin Bieber fans: Do not invade the singer’s personal space.

While on his way to perform a show in Barcelona on Tuesday night, the 22-year-old was riding in the backseat of a car with the windows down. As expected, the street outside the venue was lined with fans and photographers trying to get a glimpse of the mega-star; however, one Belieber became a little too excited, and consequently walked away with a bloody face.

In a video obtained by TMZ, we can see Bieber’s car slowly passing the crowd of fans when all of a sudden a young man approaches the vehicle and sticks his hand into the opened window trying to touch the singer. Bieber wasn’t having it. Moments after the fan reached out, we see Bieber’s fist fly out of the window, hitting the dude square in the face. The fan retreats with what appears to be a bloody lip.

This isn’t the first time Biebs has gotten into a physical altercation. Remember that time he was filmed fighting a guy who was twice his size? Or his highly publicized run-ins with the paparazzi? And who could forget that time he fled from a fight with Orlando Bloom?
