Recently, T-ara surprised fans with the promise that they will appear in bikinis if they rank first.
In the live episode of KBS 2’s Music Bank hosted by Lee Jang Woo and After School’s Uee, Super Junior and T-ara competed for the top ranking.
T-ara asked Super Junior, “What kind of special performance will you give if you rank first?” The boys answered, “To celebrate the upcoming Olympics, we’ve prepared two things: the first thing is swimming and the second one is a performance of weightlifting.” The girl group favored the latter choice.
Then they continued, “We’ve also prepared something special. Celebrating the Olympics, the first thing we’ve prepared is bikinis and the second one is nothing.” Immediately, Super Junior added, “We surely hope you rank at the top, and your special performance should be your encore,” inspiring a big laughter.
The episode also featured spectacular performances by BOB4, Ntrain, Jung Ha Yoon, F.I.X, C-Clown, Glam, A-Jax, 2BiC, Gangkidz, Big Star, B.A.P, Nu’est, December, NS Yoon-G, Dalshabet, Gil Me (feat. Eun Ji Won), ZE:A, A Pink, 2PM’s Jang Woo Young, After School, and Sistar.
