North Korean leader Kim Jong Un's daughter made a public appearance again, this time with missile scientists and more honorific titles as her father's "most beloved" or "precious" child.

She's only about 10, but her new, bold photos are deepening the debate over whether she's being primed as a successor.

The daughter, believed to be Kim's second child named Ju Ae and about 9 or 10 years old, was first unveiled to the outside world last weekend in state media photos showing her observing the North's intercontinental ballistic missile launch the previous day with her parents and other older officials.

KCNA described her as Kim's "most beloved" or "precious" child, a more honorific title than her previous description of "(Kim's) beloved" child on its Nov. 19 dispatch.
