Li Zhien (/ Lee Ji Eun), stage name IU, Korean female singer, actor and host.
Born on May 16, 1993 in Seoul special city, South Korea, I like listening to music very much from kindergarten. I often sing karaoke with my father. In the first grade of middle school, she stood on the stage of school performance with the recommendation of her PE teacher. From that moment on, she had the idea of becoming a singer.
