Lee Hwi Jae chose ballet as a way for the twins to improve their flexibility. But what stole their attention were the shiny tutus. Suh Un also took a leaf and put it in his hair to match his tutu. They even followed along to the ballet teacher's directions by lifting their arms up high, impressing their dad.

Catch these little ballerinos this Sunday at 4:50 PM KST!
