Justin Bieber Cancels Concert Due to Sickness

The Biebs is down! We repeat, Justin Bieber is down!

The seemingly indestructible Bieber canceled a show scheduled for tonight at the New York State Fair in glorious Syracuse, NY. He will instead perform Wednesday night.

A statement of the Fair's website reads, "Due to an illness and under doctor's orders, Justin Bieber has been forced to re-schedule his Sunday, Aug. 29 concert at the New York State Fair to Wednesday, Sept. 1, at 7 pm."

Bieber alluded to the illness on his Twitter page yesterday, writing, "Been super sick lately but u guys are carrying me. thank u for the love."
