According to several local reports and videos, Justin Bieber was attacked by a fan during his Believe World Tour concert in Dubai. Several reports state that Bieber was performing on his piano when his attacker, a 'youth in a white shirt and jeans', rushed him on stage. There's no word on how this attacked managed to get so close without security stopping him, but he was immediately hauled off by security before he could do anything to Bieber.

In the altercation, Bieber's piano was supposedly knocked over and removed from the stage. However, all the reports state that after the stage had been cleared and the area had been secured, Bieber continued his performance like nothing happened. For all everyone says about Justin Bieber, that is a mark of a true professional. Now, if only he exhibited that kind of professionalism all the time.
There's no confirmation yet on whether the attacker was actually just a crazed fan or someone else, but for now reports have just been calling him a fan. Meanwhile, Justin's on again/off again girlfriend, Selena Gomez, has been busy with friends while Justin has been off on his Middle East leg of the Believe tour.

After hearing this news, it wouldn't be surprising to see Bieber cut his tour short or Gomez fly out to meet him in Dubai.
