TaeTiSeo participating in "Super Star K 4" was revealed.

In the pictures that Mnet revealed today of "Super Star K 4," TaeTiSeo was in it, catching the attention of many fans.

In the picture, TaeTiSeo (Taeyeon, Tiffany, Seohyun) are sitting next to Lee Seung Chul and other judges, smiling at the contestants of "Super Star K 4."

Taeyeon is wearing a white mini dress with a cushion on her lap, and Tiffany is wearing a blue sleeveless dress. Seohyun is wearing a white dress as well, showing off her beauty.

This picture was much more meaningful because it was held in the army base. When TaeTiSeo came out as judges, the soldiers screamed in joy.
