There are an innumerable number of people who lip-sync along in the MV, many faces you'll easily recognize. You can watch the MV for yourself to spot every one of them, but let's just say there's a certain Girls' Generation member and many talented rappers (who have also appeared on SMTM like Vasco himself).
"Whoa Ha !" is the pre-release track to his upcoming 'Mad Max' mixtape, so stay tuned. Check out the MV above, and let us know which cameos you spot!
