Singer Son Dam Bi revealed a picture taken with After School's Nana.

Today, Son Dam Bi posted on her Twitter, "The long filming from yesterday. With cutie Nana," along with a picture.

In the picture, Son Dam Bi is wearing a flower-print dress, smiling brightly. Nana, on the other hand, is wearing a striped shirt, making a rather serious face. The two seem to be equally superior in beauty.

Internet users who saw this commented, "This picture shines" and "I didn't know you two are close."
