4minute's HyunA recently sat down with Seoul NTN for an interview, where she expressed her thoughts particularly about her mature facial transformation for her latest comeback title track, "Bubble Pop". HyunA stated, "I stopped maturing at 14; my facial features haven't changed since then. Because my facial development finished so early, people would often say to me, 'Baby face didn't change', which always saddened me. Now that I'm finally 20 this year, more and more people are telling me that my face is finally matching my age, which I like hearing." Not only HyunA, but other members of 4minute have also recently become a hot issue for their beautiful 'passport pictures', despite all being bare-faced. She laughed and said, "I recently made a new passport, so I don't think that's the case anymore." She continued, "My last passport picture was during my chubbier childhood babyface days. But now that 4minute participates in a lot of traveling with more schedules overseas, we thought airport authorities could begin questioning my passport picture so we decided to get it updated."
