Singer IU was revealed to be part of the girl group Five Girls in the past. 

In Mnet's "Beatles Code 2" aired on July 23, After School member Uee revealed that her first kiss was in the days of Five Girls. She shocked everyone by revealing that her first kiss was with a male idol from the same agency. At this, the MCs tried to guess which male idols were in the agency, and Uee said, "My agency had a lot of trainees. IU, U-KISS' Soohyun, Juniel, 4minute's Heo Gayoon and more."

She continued, "I want to keep it a secret for myself," but she continued revealing secrets by saying "Back then I was a sophomore in high school and that person was a student too. He used to work as an idol but I didn't run into him even once after my debut," arousing laughter.

Internet users who saw this commented, "IU used to be in Good EMG, they must be so sad they lost her," and "IU and Uee used to be in the same agency? That's interesting."
