Seriously, correct me if I'm wrong, but I've made a pretty interesting observation: I haven't found a K-Pop idol yet who has an outie belly-button. Not to say that there aren't outie K-Pop idols, but they just haven't been photographed showing off their stomachs. Interesting, huh?
EDIT:
Girls' Day Hyeri seems to have a bit of an outie, but I'm entirely sure...a near first?
