{blackbabes} Jay Z & Beyonce -- We Run This Town ... Insane Crowd Proves It (VIDEO)

Either Beyonce and Jay Z need to stop going out in public, or NYC needs way more cops for NBA All-Star Weekend -- 'cause they damn near started a riot Thursday night just by stepping out of their SUV.

The scene in this video is ridiculous ... the massive crowd rushes the barricades in unison when Jay and Bey's ride pulls up outside Jay's 40/40 Club. Then, maybe to avoid even more chaos -- they walk in separately.

So, who was the opening act, and who headlined? Watch the vid to find out, but there's no doubt ... they're the reigning king and queen of NY.

Makes ya wonder why the hell they're moving to LA, right?
