Girls flocking to Syracuse this weekend got devastating news today: Justin Bieber is postponing his concert at the New York State Fair -- originally set for 7 p.m. tonight -- until this Wednesday, according to TMZ. He's reportedly suffering throat trouble and simply too under the weather to sing. (No word on whether medical intervention involved reaching under his bangs to feel for a fever.)

Naturally, fans of the 16-year-old pop star are atwitter on Twitter, and their idol is trying to keep them in the loop.
