Girl group SISTAR made a surprise appearance on KBS 2TV "1 Night 2 Days" with completely no makeup on.

In KBS 2TV "1 Night 2 Days" aired today, SISTAR came out to help Kim Jong Min carry out his mission.

On this day, Kim Jong Min failed his mission of having to meet 2NE1. So he instead had to meet SISTAR and carry out the same mission.

SISTAR seemed very shocked when Kim Jong Min showed up in Miss Korea's outfit. Even though they were wearing no makeup, they confidently stood in front of the camera and helped Kim Jong Min carry out his mission.
