SEE ALSO: NU'EST's JR and Baekho reportedly guesting on 'Happy Together 3'

JR said, "While I was going home after school, I was recruited on top of the hill around the school. It was a street casting. A casting manager approached me all of sudden and asked me if I had any thought of becoming a celebrity." He continued, "I heard this after but apparently, my middle school appeared in the casting manager's dream so that's why he/she were at the school."

HyunA also revealed how she got into the entertainment industry. She said, "It was a special case for me. When I was younger, I wasn't too outgoing so my dad sent me to a dance school. There was a clip that was released on television of us dancing and practicing in the background. After seeing that, an agency contacted me."
