This is some Bieber fever style shiz!
Trey Songz was set to sign autographs at a record store in Philadelphia last night, but the event was canceled by authorities after the fans got too out of control!
Philly PD shut my signing down here because it's too crazy. I apologize to all and ask u 2 please understand I don't want anyone 2 get hurt
Unfortunate, but sometimes it's better to play it safe!
We're glad no one was hurt!
