TVXQ's Changmin, SHINee's Minho, and EXO's Suho will be making a variety program guest appearance for the first time in a while!

The three stars are scheduled to appear as guests on an episode of JTBC's 'Hidden Singer 7' featuring Super Junior's Kyuhyun as the highlight artist. On this episode, Changmin, Minho and Suho will have to try to guess which singer is the real Kyuhyun behind the curtains!

JTBC's popular music quiz program 'Hidden Singer' invites well-known singers, as well as some of their best voice impersonators, onto the show each week. The singer must compete against his or her impersonators to make it to the final round of the guessing game and prove that their skills are unrivaled!

Do you think some of Kyuhyun's closest friends will be able to guess Kyuhyun's voice behind the curtains?
