Watch | Justin Bieber punches fan in Barcelona

Looks like pop icon Justin Bieber gave a male fan a little too much after throwing a punch at him while arriving for his concert in Barcelona. Footage appears to show the 22-year-old Canadian pop star punching the male fan through the open window of his car as he was driven by a chauffeur to the Palau Sant Jordi for latest stop on his 'Purpose' tour. The enthusiastic fan can be seen reaching out to touch the singer while the car rolls past at slow speed, but Bieber reacts with a jab that makes contact with his face. As the car drives away, the guy is seen touching his mouth in apparent shock before turning to face the camera and dramatically showed his bloodied lip. This is not the first time the pop star has involved in an immature issue.
