A male fan at a recent fan signing event reportedly told Eunseo that she looks like the soccer player. Eunseo, apparently not able to hide her hurt feelings, burst into tears and eventually stepped out of the fan meeting. Netizens have often claimed that Eunseo looks like Swedish soccer player Zlatan Ibrahimović.

According to Allkpop, after the event, the fan allegedly officially apologized via DC Inside. He explained that he lacked information about Cosmic Girls because he just recently became their fan. He further said that he did not know Eunseo hated the comments about her resemblance to Zlatan that much.

The male fan reportedly explained further in detail what happened. He clarified that when he asked Eunseo if she knew the soccer player, her facial expressions got really serious. He further stated that when she started asking why, he knew right then that he has said something that should not have.

In a past Cosmic Girls' fan meeting, a male fan apparently also pointed out their resemblance. The fan accordingly even shouted out to Eunso if she knows Zlatan. When the other fans started laughing, the Cosmic Girls reacted and asked who Zlatan is. The male fan responded that he is a soccer player. After that incident, the netizens apparently continued to call Eunseo as the look-alike of Zlatan Ibrahimović.
