It's been a great week so far for girl group Kara! After nabbing the number one spot by close margins for the past two days, these girls continue to up the ante each time they perform on stage. Their single Lupin has been all the rage since its release and has continued to maintain high positions on various online music charts. Despite their busy schedules, the ladies of Kara keep bringing us a full dosage of fierce every time they perform their hit single! You'd think the crowd would get tired of screaming for their girls all the time, but it seems as though they only get louder with time! Check out their performance below. http://www.youtube.com/watch?v=6S5Ki-yTQMo
