MBLAQ's Lee Joon is known for making the ladies swoon with just a simple flex of his muscles. But it seems like he's met his match in a little girl named Dayoung.

On January 26th, KBS JOY will air a new episode of 'Hello Baby Season 5' - a reality show that sees the members of MBLAQ become proxy parents to three young children.

Lauren and Dayoung, two of the little girls on the show, both seem to favor MBLAQ's�G.O. As such, Dayoung couldn't hide her jealousy when she saw G.O. playing with Lauren.

Noticing how upset Dayoung was, Lee Joon took it upon himself to try and cheer her up with his "muscle aegyo". Unfortunately for him, Dayoug looked less than impressed with his musculature, and even scrunched up her face.



Check out the full scene when the episode airs at midnight on January 26th KST!
