This may be the creepiest thing ever posted to the Internet.
Thousands of obliging Tweens have since posted their clips.
But one among all the others has caught the Internet's attention.
This fan - this terrifying fan - has a unique staring (and singing) style which is something to behold. Possibly intentional, possibly not, but definitely very strange, it's utterly hypnotic. Perhaps literally.
The video is now about to go 'viral', having received 5,000 views in just over 10 minutes late on Thursday afternoon.
According to one Reddit user the singer blinks a total of nine times throughout the entire video.
Justin's favourite video will win a prize and be featured on TV. But clearly the Internet has already chosen.
Seen something creepier on the internet? Let us know in the comments.
