B1A4 CNU rejects the idea of having a guest star mom. 

On the 24th KBS Joy show, "B1A4's Hello Baby" had their production announcement conference.

On this day B1A4 was asked, "In the past seasons we've had 'day moms' feature as guests. Which stars would you want to guest star?" B1A4 replied, "We want our own mothers to star.'" Their honest answers made everyone laugh.

When the MCs persisted, "How about out of the celebrities?" B1A4 replied, "We would want MBLAQ's Seungho to come. He gave us a lot of advice before we aired on 'Hello Baby,'"

CNU added, "I kind of don't want any to come. The kids barely recognize us. I'm worried that if more new faces show up, the kids might be flustered." He revealed a perspective that others hadn't brought up.

"B1A4s' Hello Baby" is a show where the members take care of two five year-olds from the countryside. The members and the children wander around Seoul as they get assimilated the best they can.
