Group Rainbow's Woo Ri revealed her cuteness through her very first short haircut.

In preparation for Rainbow's new song, "Tell Me Tell Me," Woo Ri confidently cut off about 40cm of her long hair to try short hair for the first time. Many have been complimenting her new hairstyle, pointing out that she looks much younger than before.

Woo Ri has been rising in popularity with the nickname 'national grandma' for her chill and relaxed personality and for being the oldest in KBS 2TV entertainment program, "Invincible Youth 2."
