Girl group G-Friend revealed a picture taken after appearing on a radio program.

On Feb. 3, G-Friend appeared on KBS CoolFM "Jang Dong Min & Lady Jane's 2 O'Clock" as the guests.

On this day, Lady Jane said, "G-Friend is the youngest guest we've ever had on our show. The leader was born in 1995 and the youngest one in 1998."

To fit the title of being the youngest guest, G-Friend showed off their cute and innocent charm through the live singing of their debut song "Glass Bead."

After the show, G-Friend posted on their Twitter, "Jang Dong Min & Lady Jane's 2 O'Clock~ We were so nervous but it was that much more fun! How was our acapella? We'll practice more so that we could give you even better music ^^"
