We're told they're also reviewing footage from the incident.

A woman has gone overboard from a cruise ship loaded up with EDM acts like Skrillex, G-Eazy, Diplo and Major Lazer -- and their fans.

We're told the woman fell from the Mad Decent Boat Party, which took off Wednesday from Miami bound for Cozumel. Our source says 3 rescue boats have been deployed to start searching for the victim somewhere in the Caribbean.
