Singer IU and actress Yoo In Na showed off their friendship.

"Chef Won Il's dear bread. And IU and In Na. What are the four of us doing? Take Care Of My Fridge?," posted the fashion designer Go Yong Tae on Friday along with a picture.

In the picture, IU had visited the filming site of "Fashion King" to support Yoo In Na. The two are showing off their sister-like looks and unchanging friendship in the picture.

"Fashion King" is a show where designers and celebrities form a team together to come up with a collaborated look every week.
