An old photo of�IU's has become a hot topic, as it showed the singer from her debut days. Uploaded onto an online community board, the photo's caption read, "IU shortly after debut chatting with fans." Dating from sometime in 2009 (which is when IU first launched her career), the photos caught IU chatting with fans on a program. Her chubby cheeks, blunt bob, and girly tee brought further attention to her youthful charm. IU's fans commented, "She does look like the nation's little sister," and "It was only 3 years ago, but it seems like she's grown up so much already." IU will be making her music program comeback through 'Music Bank' tonight, so stay tuned for more updates! Source + Photo: Newsen via Nate
