Leaders in the hermit kingdom are often very secretive when it comes to their significant others, but Kim Jong Un often has his wife join him and allows photographs.
North Korean media revealed in July that he was married to Ri Sol Ju — a former cheerleader and singer — but no one knows exactly when they were married, according to NBC News.
South Korean intelligence believe the couple probably married in 2009 and already had one child. There are rumors Ri Sol Ju gave birth to a child in 2012, with many believing it was a girl.
The couple is believed to have had another child, in 2015.
