Yoon Mi-rae has threatened to sue Sony Pictures Entertainment for using one of her songs in the controversial movie The Interview without permission, according to the South Korean news agency Yonhap.
The Interview is a comedy about the assassination attempt of North Korean leader Kim Jong-un.
The Interview had its launch cancelled after a major cyber attack at the hands of a group calling itself the Guardians of Peace.
The hackers threatened to carry out a terrorist attack on cinemas that showed the film on its scheduled release date of Christmas Day.
The US accused the North Koreans of being behind the hack, something the country denies.
