They been drinking....They been drinking...Bey & Jay Party in the A...

 Jay Z and Beyonce bought drinks for their entire V.I.P. section last night in Atlanta ... and their bill totaled your annual salary.

Yonce and HOVA hit up Club Reign in Atlanta on Friday -- and our club sources say the duo dropped ALMOST 100K on bottles of Dusse and Ace of Spades for their section.

Jermaine Dupri and Bow Wow partied with the power couple as well ... and they were joined by Dream and Trey Songz.

Best part -- Bey and Jay dancing to their own song.
