We don't even really know when he was born, but it is estimated to be either 1983 or 1984. His grandfather was often seen with his wife in public and in photographs with their children. But his father and predecessor Kim Jong-il was a lot more elusive. He was thought to have had at least four different partners - Song Hae-rim, Kim Young-sook, Ko Young-hui (Kim Jong-un and Kim Yo-jong's mother) and Kim Ok - but his relationships were mostly kept out of the public eye.A mysterious video of Kim Jong-nam's son, Kim Han-sol, then emerged online - making a male heir even more important for the North Korean leader.
