Sung Yu-ri (born March 3, 1981) is a South Korean actress and singer. She made her entertainment debut in 1998 as a member of the now-defunct K-pop group Fin.K.L. Sung turned to acting in 2002, starring in television dramas such as Thousand Years of Love (2003), The Snow Queen (2006), Hong Gil-dong (2008), and Feast of the Gods (2010).
Sung was born in 1981 in Tübingen, Baden-Württemberg, West Germany. Her father Sung Jong-hyun, a prominent professor of theology at the Presbyterian College and Theological Seminary, was studying at the time in West Germany. Sung's family returned to South Korea when she was four-years-old and she grew up in Gangdong District, Seoul. She attended Myung Elementary and Middle School, Kwang Nam High School and graduated from Kyung Hee University with Post Modern Music Major in 2005.
When Sung was a high school student, she began her entertainment career in 1998 as the youngest member of the four-member K-pop girl group Fin.K.L (which stood for "Fine Killing Liberty"), one of the very first Korean idol groups. Fin.K.L quickly rose in popularity, releasing four albums (Blue Rain (1998), White (1999), Now (2001), Eternity (2002)), and various singles, live concert albums and compilation albums. But after the release of their fourth album, Sung and fellow band members Ock Joo-hyun, Lee Hyori and Lee Jin began doing solo activities.
