There's no stopping T-ara this year, as right till the very last day of 2011, they'll be working hard on the various projects. Despite their busy schedule preparing for their Japanese concert, drama filmings, and year-end ceremonies, the girls still took time off to practice for their musical, 'Roly Poly'. Choreographer Kang Ok Soon stayed with the girls at their rehearsal room until late into the night, thoroughly preparing them and the staff for a successful show. While some were worried the girls wouldn't have enough time to rehearse because of their insanely packed schedule, the fears were put to rest, as producers assured everyone that they were satisfied with the progress the girls were making. The girls have been practicing their script in the car and dorm and any spare moment that they have got. 'Roly Poly' will begin at the Sungnam Art Center starting January 13th, 2012. If you haven't already, be sure to check out their trailer here. [gallery link="file" order="DESC"] Source + Photos: Sports Chosun via Naver
