With 4minute due in Hong Kong tomorrow, I didn't think HyunA would be bringing it on Music Bank tonight. Boy was I pleasantly surprised when this sexy little thing brought it and changed things up. Not to mention, she was rocking that sexy outfit from her music video. HyunA sure is working hard along with the rest of her group mates. I gotta give it up to both HyunA and 4minute, they are really shaking things up all across Asia right now. Anyway, check out HyunA's undeniably sexy performance of Change below: http://www.youtube.com/watch?v=7HzxXAsCgrU
