When Eunjung was asked if she was jealous of Jiyeon, the female idol answered, "I think it's better to work hard when I'm working and be fully prepared before looking for a guy. I started thinking this way after adding another year to my age."

Chae Yeon then chimed in, "If you keep thinking that way, then you're going to become like me," drawing out laughter from the guests as Chae Yeon is 37 and still single.

Meanwhile, Jiyeon made her relationship public with actor Lee Dong Gun last year after getting caught together several times with acquaintances.
