Beyonce just pulled off an AWESOME surprise at a Target in Harlem … where she unexpectedly appeared at an event for the Boys & Girls Club … and led an impromptu dance party!!!
Beyonce’s choreographer was in the middle of conducting a dance lesson for the group … when the pop star suddenly walked on stage … AND THE WHOLE PLACE WENT NUTS!!
We’re told Beyonce hung out for roughly 15 minutes — and afterward, she bought a handful of her new CDs and handed them out to the group.
Check out the video — the reactions are priceless!!
