Yoon Jong Shin's reps responded, "Lee Seung Chul and [Yoon Jong Shin] keep getting labeled as a being on bad terms but just because they haven't contacted each other in a while, is it considered being on bad terms? We are not too concerned about the content of Lee Seung Chul's twitter, and there is nothing to feel angry about."

The tweet was apparently a direct response to Kim Ye Rim (Lim Kim)'s somewhat shocking teaser for "All Right" in which the singer went pantless,�with close up shots provided at the almost see-through underwear. It was revealed to be a marketing strategy more so�than an MV teaser as the full MV ended up not having any such scene.

The rumors of Yoon Jong Shin and Lee Seung Chul's discord have been further fueled by the fact that Lee Seung Chul will return to 'Superstar K' for season 5 while Yoon Jong Shin has decided not to return as a judge once again. The two artists have been together as judges from seasons 1 to 3.�

Yoon Jong Shin's camp stated, "Although [Yoon Jong Shin] received the offer early this year, our agency is currently busy preparing for various projects to be released this fall. Due to scheduling conflicts, [Yoon Jong Shin] rejected the offer."

In addition to Kim Ye Rim's solo debut, Yoon Jong Shin's agency is currently busy preparing for the comebacks of�Park Ji Yoon, Jo Jung Chi, Hareem, Yoon Jong Shin himself, and more.
