Group Big Bang's member G-Dragon encouraged his fans to watch "Infinite Challenge."

"Ah, don't miss Infinite Challenge music festival today. HwangTaeG, OMG, Infinite Challenge, 2015 Youngdong Music Festival," posted G-Dragon on his Instagram on Saturday along with a picture.

In the picture, Kwanghee, Taeyang, and G-Dragon are lying down on grass, covering their faces with the 1988 Seoul Olympics hats. They are wearing colorful tops of red, yellow, and blue, creating a cute image of the same-age friends.

The three performed "OMG" on MBC "Infinite Challenge" on this day.
