Singer Yoon Gun has been chosen to take the place of Psy as a judge on "Superstar K4."

Starting on October 19, Yoon Gun will be the judge along with Lee Seung Chul and Yoon Mirae for Mnet's "Superstar K4."

With Psy leaving for Australia on October 15, the "Superstar K4" staff was in a dilemma to find someone to take over his position. 

The staff commented, "We have finally found a talented musician to take the place of Psy as judge. We are not sure if the new judge will stick around until the end. We will just have to see how it goes."
