Block B's member Zico tried taking a picture of singer Jung Joon Young sleeping.

On September 24, Zico posted on his Twitter, "The rock star that woke up as soon as he heard the shutter" along with a picture.

In the picture, Jung Joon Young is lying down on the sofa, having just woken up from his sleep. Zico is making a nervous look at the camera trying not to wake him up but had failed, arousing laughter.

Internet users who saw this commented, "I like Zico's outfit," "Jung Joon Young really looks like he just woke up," etc.
