Yesterday was quite a day for the girls of T-ara! After meeting up with 2PM, performing a brand new version of their hit single Bo Peep Bo Peep, and winning their first K-Chart, one could easily say the girls were pretty much experiencing a natural high. With all their success on yesterday's show with the traditional version of the song, I guess one could even say their hanbok outfits could be considered their good luck charms! These girls started the year off right and they're keeping the momentum going on today's stage for Music Core. Check out their performance! If you are wondering, Jiyeon was absent due to filming for her drama, God of Study which debuts on 4th January. Do show your support for her and the drama when it airs!
