A crazed fan stormed the stage and attacked Justin Bieber from behind as he performed during a concert in Dubai today.

In several videos of the incident posted online, Bieber, 19, is seen sitting at the piano when a youth in a white shirt and jeans blindsided the unsuspecting pop star.

Security guards quickly descended and hauled off the attacker, but not before Bieber's piano was flipped over in the ruckus.

The Biebs managed to free himself and rushed to the side of the stage, still singing.

According to reports, Bieber was rattled but managed to finish the song with his eight-piece band as the offender was taken off stage.

He took a three-minute break, then returned for an encore and ended the show with his hits "Boyfriend" and "Baby."

It was Bieber's second show in Dubai in as many days and his first performance in the United Arab Emirates.
