Psy has canceled his plans to appear as a judge on 'Superstar K4' due to scheduling conflicts with his overseas promotional activities.

He was unable to appear on the second live broadcast of the show. Psy recently left for Australia to make a guest appearance on 'The X-Factor Australia' on the 15th and will be busy with his activities in the US starting on the 18th, making it virtually impossible for Psy to come back to Korea in time to act as a judge on 'Superstar K4'.

It has been revealed that the show's staff is currently in discussion over whether to keep the current panel of judges with the remaining two celebrities or bring in another replacement.

Netizens commented, "I figured it would be difficult for Psy to appear as a judge for 'Superstar K4', and I guess I was right", "After hearing the news, I feel less inclined to watch the show", and "If Psy won't be judging, who will".
