Girl group Girls' Generation's members Yoona and Yuri revealed a sister-like photo together.

"Weekly idol, YoonYul, Yoona~," posted Yuri on her Instagram on Wednesday along with a picture.

In the picture, the two are showing off their matured and increased beauty. Both are holding up V-signs and are winking at the camera- making them look like sisters. Yuri seems to be encouraging her fans to watch them on "Weekly Idol" through the picture.

Girls' Generation is currently actively promoting their new song "Lion Heart."
