Girls' Generation made an appearance on "Superstar K4."

Yesterday's episode of "Superstar K4" featured Girls' Generation member Taeyeon, Sooyoung and Seohyun visited the TOP 6 contestants.

In the episode, the contestants were assigned to perform a live stage performance entitled "My style" and Taeyeon, Sooyoung, and Seohyun made a surprise appearance to deliver a related mission, performing their own version of the hit song "Gee."

TOP 6 contestants formed two separate teams to practice and performed their own versions of "Gee" on stage in front of the three members. The winners were determined by the girls based on who displayed their own unique talents. In the end, the team Dickpunks and Roy Kim was selected as the winner.

The three members Taeyeon, Seohyun and Sooyoung afterwards spent short time with the contestants shaking hands and taking photos.
