YouTubers Yes Theory have confessed up to staging the photo, flying Bieber lookalike Brad Soussa to Los Angeles to shoot the fake picture.
But the prank didn't stop there, with a video posted on Sunday detailing how Yes Theory emailed the picture to countless news outlets and posted it on Reddit where it went viral.
One of the members even gave interviews to journalists, claiming to have taken the photo after spotting Bieber sitting alone in a West Hollywood park.
While Bieber is yet to comment on the viral photo the singer's manager Scooter Braun retweeted the YouTuber's video and commented: "And now all my friends can stop asking."
In another tweet Braun shared a video chat with Yes Theory in which he revealed he had known the picture wasn't of Bieber but decided to play along.
