On July 22nd, MBLAQ shared two hilarious unreleased photos from their "Mona Lisa" jacket album. Dressed in their respective parodies of historical figures Papillon and James Dean, Seungho climbs confidently on top of the table which G.O. is sitting at. Surprised, G.O. shoves his fist in his mouth in an act of shock. Since their published album jacket photos conveyed such a serious atmosphere, fans couldn't help but chuckle over this fun set. Currently promoting "Mona Lisa", the boys are also said to be diligently preparing for their first concert next month.  A representative of J. Tune Camp said, "Amidst their busy schedules, they're all using whatever time that's left over to prepare for their solo stages." MBLAQ will be holding their first concert on August 20th.
