Justin Bieber OK After Dubai Stage Crash

Footage shows fan grabbing Bieber on Sunday night, knocking over piano while trying to avoid security.

The show must go on. Justin Bieber proved that age-old showbiz maxim on Sunday night during a show in Dubai when an excited fan ran up on stage and tried to hug him from behind.

The singer looked surprised in a fan video posted online (which has since been taken down), but the incident didn't last long, as a security guard quickly rushed out and grabbed the male Belieber in a bear hug. During the scuffle, Bieber's grand piano was knocked off its pedestal and upended. The singer, however, simply stood up and kept the music going as the stage intruder was hustled away.

"Dubai. Nothing stops the show," Bieber tweeted after the incident at Sevens Stadium. "2 more to go."

Is Justin Better Off With Or Without Selena Gomez?

Bieber's musical director and guitarist, Dan Kanter confirmed that it was no joke, adding, "It wasn't a prank. Someone ran on stage during 'Believe' and the piano got knocked off its platform. Everyone is fine. No need to worry!"

The director of his "Believe 3D" movie, Jon M. Chu, also weighed in, tweeting, "Wow. @justinbieber was the ultimate professional again as he is almost tackled on stage by a fan and keeps performing. Nice work my friend!"

After the interruption, Bieber finished the song and went on to complete the show with encores of "Boyfriend" and "Baby." He moves on to a pair of shows in Cape Town, South Africa before returning to North America for a string of dates in June and July.
