2AM member Jo Kwon revealed that JYP shows favoritism among his singers.

On the latest episode of KBS2TV "Happy Together 3," Jo Kwon revealed that JYP treats girl singers differently from guy singers.

Jo Kwon, when asked about his discontent, said, "Park Jin Young is only nice to the girl singers."

He continued, "When the male singers go into a recording session, JYP tends watch us more closely and shows a rather annoyed facial expression. But when Wonder Girls member Yeeun comes in, he greets her with a smile and laughs."

Jo Kwon also revealed that it is harder for him behind stage rather than when on stage.

He said, "After 2AM finishes a performance on stage and goes down, JYP calls us." He continued, "JYP makes us sit down with a pen and paper in front of the phone."

He continued on saying that, "JYP gives us a ranking from 1 to 10 about our performance and tells us what parts we need to correct."

The episode will air on July 12.
