Supposedly, the whole area was incapacitated because so many fans were gathering in swarms like it were a national holiday.

IU's agency Loen Entertainment said, "IU had a guerilla date for 'Entertainment Weekly' on the 9th.  We don't know the exact circumstances of what happened on location, but we know many fans gathered."

It is no surprise she attracted such a huge crowd as her latest third album 'Modern Times' has succeeded in an all-kill on the music charts.  Make sure you watch the MV here if you haven't already!
