We knew that Justin Bieber had some pretty ferocious fans, but their newest achievement is nothing short of impressive. Tickets for Justin’s upcoming U.S. Believe Tour went on sale Saturday at 10 a.m., but were gone in one hour.

Fans also gobbled up tickets for Bieber’s Madison Square Garden shows, November 28th and 29th, in 30 seconds!

Justin’s tour manager then took to Twitter to express how amazed he was by the fan response:

“Blown away. Now we are gonna make sure the ‪#BelieveTour‬ is as epic as possible. Thank u for supporting the kid. Amazing.”

Just how epic will the U.S. Tour get? We’re not certain. But one thing is for certain — there’s no shortage of Beliebers who are waiting anxiously to find out.
