Actress Song Hye-kyo, who made a surprise announcement of her wedding plans with actor Song Joong-ki, recently made a secret 100 million-won donation to a children's hospital, sources said Thursday.
The actress made the donation to the Seoul National University Children's Hospital in May, on the occasion of Children's Day, according to hospital officials. Song reportedly asked the hospital to keep the donation a secret.
Last year, Song contributed her voice to KBS 1TV's children's documentary titled "May, Children" as a narrator. The program captured the daily lives of the medical staff and the child patients at the hospital.
