Yoo Chae-yeong
South Korean actress and singer (1973–2014)
Yoo Chae-yeong (Korean: 유채영; September 22, 1973 – July 24, 2014) was a South Korean singer, actress, and radio host.
Early life and education
Born as Kim Soo-jin, she made her entertainment debut at 17 years old as part of the group Punsudeul ("Idiots") in 1989, when she was still in high school.
Career
In 1994, using the stage name Yoo Chae-yeong, she became one of the original members of the popular K-pop group Cool. She initially attracted media attention for sporting a shaved head, which at the time was a bold hairstyle rarely seen on female South Korean celebrities. Yoo left Cool a year later, going on to make up one half of the duo US in 1995. She embarked on a solo singing career in 1996, and her hit song "Emotion" (released in 1999), contributed to the nationwide spread of techno music.
As an actress, Yoo appeared in supporting roles in movies and television dramas, notably in the comedy film Sex Is Zero (2002) and its sequel Sex Is Zero 2 (2007). She was also a popular radio host on the MBC program Good Weekend, It's Kim Kyung-sik and Yoo Chae-yeong, known for her quick wit and self-deprecating humor.
In 2009, after nearly a decade of absence from the music scene, she released a new single titled Another Decade.
Death
Yoo was diagnosed with cancer in October 2013.

Why this record matters
The phrase “south Korean actress and singer (1973–2014)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q625508. VIAF identifies the subject as 8151110604237060466. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1973, 2014, 1989 and 1994.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
