'Knowing Brothers' said TWICE can't guest on the JTBC variety show because of Super Junior's Heechul.

On the November 12th episode of 'Knowing Brothers', 'The Fabulous' co-stars SHINee's Minho and Chae Soo Bin featured as guests on the show and talked about their characters' relationship. Minho said, "We're exes. We're broken up, but we're also close friends." 

Lee Soo Geun then joked towards Heechul, "Because of you, that one group can't appear. I want to see them so much. We miss them so much," referring to Heechul's past relationship with TWICE's Momo.

Lee Jin Ho added, "It's probably not just that group. It's just because he didn't get caught with others." Heechul responded, "I'll be back next week. Goodbye."
