ZE:A's Kwanghee revealed his supposed close relationship with Psy on 'We Got Married 4'.

On the January 12th episode, the couples on the show held a special performance in Hawaii. On top of the traditional Maori and Tahiti dances, they also danced to Psy's "Gangnam Style". The other professional performers and audience members instantly recognized the global hit and had no problem joining in on the "horse dance."

Kwanghee commented, "Irrespective of nationality, we all danced the 'horse dance,' which was fascinating to me. I was thankful to Psy hyung." When asked if he knew Psy, Kwanghee answered, "We're close. He treats me really well... but I don't have his contact information at the moment. I usually don't call world stars," causing laughter.
