T-ara's Eunjung, Hyomin, and Jiyeon joined the 5dolls for a collaboration stage on this week's "Music Bank." The Core Contents Media labelmates will be collaborating all week long for "I Mean You" as a special act of support and friendship. The T-ara members revealed, "We've always wanted to perform with 5dolls because we really love the song, 'I Mean You.' We asked our agency if it was possible, and they readily agreed, which is why we're able to stand on the same stage together." Check out their performance below! Source: Newsen via Nate
