Popstar! was the ONLY press at the Roosevelt Field mall in Garden City, NY, yesterday for an autograph signing at Justice with Justin Bieber!

Editor Girl Dory, here, and I'm gonna tell you all about it!

When I got to the mall, there was a huge crowd near a security entrance on the outside of the mall! I went inside and made my way upstairs to Justice...or so I thought!

There were thousands of girls, blocking off all the ways to get to the Justice store! The food court was completely full, and girls were packed so tight it looked like a concert!

I heard a security guard say, "The event is cancelled. He's not coming." I thought, "WHAT?" I contacted his publicist and she said, "We're on our way!" I was so confused!

As well as tons of mall security, there were county police everywhere! After girls were told the event wasn't happening and ushered away, I squeezed into the section of the mall where the Justice store is. I got to the front and they had the metal gate down! The stores on either side of Justice were also closed!

As I explained that I was press to cover the event, the police told me they and the fire department had to cancel the event because of the fire hazard and chaos of the situation! There were so many girls!

It was total chaos! The event was supposed to start at 4pm and when I finally left the mall at 5:45pm, there were 4 cop cars outside, a news truck and a helicopter flying over the mall!

It was totally insane - Justin is lucky to have dedicated fans like YOU!

Unfortunately, some people were hurt from all the pushing, shoving and the number of people there.

Justin even tweeted that someone was arrested! (Read from the bottom up)

Yikes! Hopefully next time his signings will be safer!
