brought up his younger sister on the April 14 installment of SBS' 'Healing Camp.'
In relation to his family, the singer mentioned, "The whole household does not really tell others that there is a celebrity in the family. My younger sister was going through puberty in high school, so she paid a lot of attention to her appearance. Everyone called her long-haired Lee Seung Gi." Even though nobody knew she was Lee Seung Gi's younger sister, she must have had a striking resemblance to him!
