BEAST's leader Yoon Doojoon has been chosen to model for premium jeans brand Buckaroo. BEAST experienced explosive popularity after debuting with their single "Bad Girl." They are now promoting "Mystery," which is receiving just as much, if not more love from fans. It has been less than 100 days since their debut, but Doojoon has already been selected to model for Buckaroo alongside Shin Se Kyung. Doojoon was a soccer player and athlete, therefore he has an extremely tough and fit body. He is also referred to as "Stone Thighs" by the fans, which is why he is a top candidate to model jeans.
