On August 17 episode of JTBC's television show 'Knowing Brothers', HeeChul mentioned his recent dating rumors with MOMO.
During the opening of the show, one of the cast members Min Kyung Hoon said, "HeeChul might not show up today, because he might feel too uncomfortable. It's right after the dating rumors have gone around with you-know-who, so..."

After HeeChul sat down, Min Kyung Hoon playfully said, "If I'm being entirely honest here, I'm a bit disappointed with HeeChul."
All of a sudden, Min Kyung Hoon turned to HeeChul and grabbed him by his collar, then said, "How could you do that to me? What really is going on between you and her? Tell me the truth."

He continued, "If I ever get a girlfriend, then I promise to let you know. I'll tell you about it before anybody else."

Not long after the report was published, however, both HeeChul and MOMO's management agency stated that they were close friends.
