An online community board recently uploaded a photo with the title, "The first shot of IU's belly button."
The photo is of IU performing at her first solo concert, 'Real Fantasy' in June. In the photo, IU is seen with her belly exposed, cute pigtails, a ribbon and short shorts.
However, the photo showing her shirt slightly raised above her navel also showed somewhat of a chubby stomach.

Internet users commented, "Her stomach is chubbier than I thought it would be", "I guess her body is not extremely thin" and "IU's first belly button exposure?"
Recently on a tv program, IU came out and had her height and weight revealed because people kept commenting on how small and skinny she was. IU's height was 161.7cm and weighed 44.9kg. IU stated, "People say that I am just skin and bones or have the body of an elementary student, but I weigh 45kg like most female celebrities, so I have a celebrity body," which brought a lot of laughter.
