Law enforcement sources tell us the Seaside Heights PD busted Snooki moments ago for disorderly conduct.
The details of that conduct are unclear. We're told Snooki -- real name Nicole Polizzi -- is currently in police custody.
Earlier in the day, Snooki was partying on the beach with a beer bong ... only she was filling it up with Coca-Cola.
We're told she was also seen at a local bar taking "body shots."
