JQT (group)

JQT (제이큐티) was a four-member South Korean girl group under GP Entertainment. The 'J' in the group's name comes from the common letter in each of the members' names, while the 'QT' stands for 'Quality' and 'Quartet'. Three of the four members are from the disbanded group i-13, a girl group that was considered the female equivalent of Super Junior. The group originally debuted in 2009 with Min Jung, Ga Jin, Ji Eun and Min Sun. In September 2011, it was announced that Min Sun would be leaving the group to focus on a career in acting. She was replaced by Lee Jin Kyung (now known as actress Lee Sun-bin), who was previously a trainee at GP Entertainment. On February 20, 2012, it was announced that JQT's contracts with GP Entertainment expired and would not be renewed; henceforth, they disbanded.
