B.A.P's main vocal Young Jae revealed a picture that showed off his small head.

Yesterday on his twitter he wrote, "Haha. American hamburger," along with a picture.

In the picture, he is holding a hamburger in both hands and is covering his face. His whole face seems to be covered by the hamburger, showing that his head is very small.

This picture was taken in October when they attended the "KCON 2012" festival in the U.S. This picture was first released at their fan club opening ceremony. Member Him Chan had joked and said, "I can cover my face with a pizza."

After only 1 hour of posting the photo, he received over 2,000 retweets and comments saying, "King of small head" and "Best proportions!"

Last month on October 27, B.A.P held their fan club opening ceremony with 4,000 fans.
