Nine Muses is a seven member idol group signed to Star Empire Entertainment. The girls first gained interest when maknae MinHa appeared in fellow label mate ZE:A‘s music video for “All Day Long“, and then eventually debuted in 2010 with the entire group. Nine Muses has gone under several line up changes, having lost three members and gaining three more to maintain their line up of 9 girls. During these changes, the girls had spent a majority of 2011 under intense training for future comebacks. Their training has seemed to have payed off because the girls have improved tremendously and have gained quite the fan base in present time.
