The idol star was one of the guests on the March 16 airing of 'Happy Together 3'. During the show, he was asked about the gay rumors. 

Comedian Lee Soo Geun spoke up for Heechul, and said, "I work with Heechul a lot so I know very well and it's understandable that he gets mistaken (as gay)."

Lee Soo Geun further explained, "He really knows a lot of girl groups. He gives advice on their songs, outfits, etc. Not as a man but as a good sunbae. He even has video calls with Seolhyun when she has no makeup on. Every girl group member answers Heechul's video call. He also went on a trip to Gapyeong as the only male. I saw the pictures and Heechul was the prettiest."

Heechul explained that girl group members enjoy hanging out with him. He said, "They said that it's comfortable to meet me because rumors don't form. I'm close with label CEOs and some of them even ask me to get close with their artists."

He also revealed, "If I'm really interested in them (as a girlfriend) then I don't try to get close to them like that."
