After having her music video slapped with an age rating, 4minute's HyunA returns to the stage once again to perform Change on KBS Music Bank! She was also joined on stage by BEAST's resident rapper, Yong Jun Hyung! Even though the Korean community deemed her music video inappropriate, she still put on one hot smokin' performance. Just goes to show that you can't ever "change" this girl and her sexiness! Cr. Mllktea3
