Chic idols MBLAQ showed off their charisma as models for clothing brand TBJ, which, in the past, has been endorsed by popular groups like Wonder Girls and 2AM. Last January, Rain's proteges had their first filming session as TBJ models. Like other boy bands, MBLAQ was full of energy and feeling looking good at the same time. A representative of TBJ said, "Our company endorses an energetic and youthful lifestyle image, so we chose to work with MBLAQ. We were very pleased to work with an idol group who is known for outstanding fashion." Despite being clothing models for the first time, the boys showed very natural expressions. Members Lee Joon and Chundoong, in particular, caught the attention of fans with the pictures that revealed their abs. Who knew Chundoong was hiding a gun show under his clothes all along?
