Justin Bieber is getting a little bit too violent for an 18-year old. Recent news is that Justin had hit his own body guard during a concert. The said incident was all caught on camera and representatives of the Canadian crooner claim that the video was simply an exaggeration of events. What really happened during Bieber's concert that made him want to smack his own bodyguard?

From being a former YouTube sensation to today's hottest musicians in the industry, it is obvious why Justin Bieber needs all the protection he can get. Still, all the attention from crazy fans and overprotective management seems to be getting to Justin's head as of late.

Web tabloids report that the 18-year old singer had allegedly hit a working private security during his concert at Calgary. If this would be true then this incident wouldn't be the first time Justin has ever used brute force. If fans may recall, Justin had a little run in with the paparazzi last May, 2012.

Bieber may appear as someone who would never resort to brute force but that is exactly what had happened back in May 27, 2012. That time, Justin had just come from a date with his lady love, Selena Gomez. It was the usual run-in with the paparazzi however during that time things got a little bit out of control.

The Canadian crooner who had never once got pissed at paparazzi suddenly picked a fight with one. The said paparazzi were blocking the couple's van. A very frustrated Justin had then exchanged heated words with the said photographer until things got out of hand. According to TMZ, the paparazzi claimed in a report that the 18-year old had knocked him aside and fled right after doing so.

While the incident with the paparazzi in May was one thing, another heated argument involving the paparazzi and Bieber date back to July. This time, Justin was caught over speeding allegedly because he was being tailed by two paparazzi cars. Ironically, Justin wasn't filed for over speeding despite his recklessness and the chance that something could have happened that day.

Now, it involves a security officer at Justin's "Believe" tour in Calgary. In the video below, it shows Justin Bieber hitting the security guard at the left side of his head. The explanation of such behavior? Before Justin had hit the guard, the singer had handed him a pair of sunglasses which was then over excitedly given by the guard to a fan. Justin had saw this and immediately struck the side of the face of the guard.
