Beyonce -- Cheers ... to Not Being Pregnant?

Rather than simply come out and say "I am not pregnant" ... Beyonce chose to deflect the rumors once again ... this time by posting a photo of her drinking a glass of wine with hubby Jay-Z.

Rumors of Bey being knocked up have been swirling for weeks, beginning when she canceled a concert in Belgium and cited the dreaded "exhaustion and dehydration."

She also posted (and quickly deleted) a diatribe on Instagram slamming the rumors ... but at no point has she ever denied them.

This photo doesn't put the rumors to rest either ... doctors aren't completely against a pregnant woman having a glass of wine every now and again. So we ask ...
