Popular Celebrity Hits Back Hard At Lee Da In’s Public Attack

Singer MC Mong ended up taking down a photo after being publicly called out by actress Lee Da In.

On September 3, 2025, MC Mong uploaded a picture on his social media featuring Lee Seung Gi, Lee Da In, Lee Yu Bi, and Cha Ga Won, chairman of One Hundred, together. MC Mong co-founded the One Hundred label with Chairman Cha Ga Won. He had also served as the general producer at Big Planet Made, but was recently excluded from One Hundred’s operations, raising questions.

He then announced that he would suddenly be going abroad to study, citing depression and health issues. Following the photo, Lee Da In openly criticized MC Mong, showing clear displeasure. She reposted it with the caption, “Why would you suddenly post a photo that’s over a year old now and stir up noise?”

In response to the attack, MC Mong eventually deleted the photo and expressed his anger. He shot back harshly.

“Mind your own business. Whether I post a photo from a year ago or one I simply liked, before I end up hating you even more. Do you think I’d ever do something like abandoning my family, like you did?”

MC Mong and Lee Seung Gi had previously appeared together on KBS2’s variety show 2 Days & 1 Night. After Lee Seung Gi’s legal dispute with his former agency, Hook Entertainment, he transferred to the One Hundred Label under Big Planet Entertainment, putting them under the same roof once again. Meanwhile, actress Kyun Mi Ri’s daughter and Lee Yu Bi’s younger sister, Lee Da In, married singer-actor Lee Seung Gi in 2023. The couple welcomed a daughter in February last year.
