Part 1 of “Justin Bieber: All Around the World” aired last night on NBC. As far as ratings are concerned, it didn’t do to well. Also, Bieber wasn’t well at one point of the documentary either.

Justin Bieber slammed his head into a glass wall during his concert in Paris earlier this month, and now there is a scary video to corroborate the aftereffects of his injury.

In his NBC special “Justin Bieber: All Around the World” fans get a glimpse of the pop singer passing out and falling down the stairs from a concussion he sustained.
After performing one of his songs during the concert, Bieber exited the stage and hit a glass partition, but decided to continue on with his performance despite the injury.

The backstage footage of the special shows Bieber tumbling down the steps and several panicked aides rushing to the singer’s side. His manager, Scooter Braun, says in the video that the “Boyfriend” singer was unconscious for four to five minutes after he fell.

Bieber haters, that is dedication! Part two plays tonight on NBC.
