Beyonce Cancels Concert Fueling Preggo Rumors

More evidence Beyonce is with (2nd) child -- she just canceled her concert in Belgium and BLAMED IT ON DEHYDRATION AND EXHAUSTION!!!!!

Who smells BS???

Fact: The preggo rumors have been circulating for weeks ... but B has remained mum on the
situation.

Now, she's bailing on a show ... and using the D&E excuse ... commonly known in the entertainment  industry as "What you tell the media when you don't want to tell the truth."

Beyonce's rep says the singer is "awaiting word from her doctors before making a decision."

So ... congrats???
