A video of behind the scenes of Girls' Generation's photo shoot has been gaining a lot of attention.
In the video is Yoona fixing Taeyeon's outfit backstage. While fixing her clothes, Yoona teases, "Girl, you really have nothing to show." The youngest member Seohyun starts to laugh and Taeyeon shoots a sharp look, and then joins in the laughter also.
Viewers commented, "This is like some reality show," "Yoona's critique must have shocked Taeyeon a bit," and "This is a famous shoot! I didn't know there was all this going on in the backstage!"
