With the whole world talking about the belly button challenge, it's no surprise to see fit idol Jung Yong Hwa try his hand at the viral trend.
But despite his rippling muscles and toned physique, the CNBlue singer failed at the challenge -- missing his belly button by several inches.
Jung, 25, uploaded the photo to his Chinese Weibo account, with the caption, "#goodbodyifyoutouchbellybuttonfromback success!! Indeed! I, too, can do it!!!" followed by lots of happy emoji faces.
But it seems he missed the point of the challenge as his hand is nowhere near his naval. D'oh!
