Justin Bieber Gets Knocked Out: Caught on Camera!

Part One of Justin Bieber: All Around the World aired on NBC last night, with the network taking fans behind the scenes of this singer on tour.

It was mostly a fun, harmless look at how the Biebs prepares for a concert, with the exception of footage from a May show in Paris when Bieber actually ran into a glass wall... and knocked himself out!

Around the nine-minute mark in the following sneak peek you can see Justin collapse to the ground and a woman scream for his manager, Scooter Braun, who calmly assesses and handles the situation. But it's a bit scary for a few moments there:
