After much success for 4Minute member�Hyuna's new music video for her solo comeback, 'Bubble Pop!', behind the scene stills of the music video filming were released. The behind the scene cuts of the music video resembled that of a professional movie with beautiful backgrounds, and HyunA with her mature charm. Arriving into summer with provocative steps, Hyuna is attracting much attention with her song, 'Bubble Pop!', enough to evoke memories of Lee Hyori's 2003 solo debut. Acting as a couple with MBLAQ's Lee Joon in the music video, it is known that Lee Joon and Hyuna are also good friends in real life. But because they are friends, it was awkward for them to act as a couple, causing a lot of NGs. Fans can view Hyuna's sexy figure through these behind the scene stills as she shows off her hot fashion. [gallery] Source+Photos: Korea Daily via Nate
