T-ara will be switching leaders from Boram to Hyomin for their "Roly-Poly" comeback next month. Core Contents Media explained, "In order to instill a sense of responsibility in each of the members, we have decided to change the leader for each new album release. We will be passing the leader role onto members who have not been leader yet. The reason Eunjung was leader during their debut was because she and Hyomin had trained the longest with T-ara, and we felt that she would be the best fit." They continued, "Likewise, Hyomin has been chosen for T-ara's Japanese and 'Roly-Poly' promotions for the same reasons as Eunjung. We have made this decision after much discussions with both the members and our agency." T-ara will be making their comeback on July 1st with "Roly-Poly", a track composed by Shinsadong Tiger and Choi Kyu Sung. Source + Photos: Newsen via Nate
