2AM's member Jo Kwon, Sunmi, and GOT7's member Jackson revealed a picture taken together.

On August 7, Jo Kwon posted on his Instagram "Rehearsal" along with a picture.

In the picture, the three were all making different shocked faces. Jo Kwon was wearing round glasses and looked surprised and Sunmi was covering her cheeks with her two hands. Jackson was wearing a fancy hat.

The three will be performing at the '2014 JYP NATION' concert on August 9 and 10 with all the other JYP artists.
