Kim Jong Un married in 2009, according to intelligence service

(CNN) -- North Korean supreme leader Kim Jong Un married 23-year-old Ri Sol Ju in 2009, according to a South Korean lawmaker on Thursday. The curiosity over Kim's wife started several weeks ago when North Korean state television and news agencies showed video footages and pictures of an unidentified woman attending official events by Kim's side. The name of the mystery woman was only announced Wednesday as Ri Sol Ju by North Korean state television. Details about her remained unknown until Jung Chung-Rai, a South Korean lawmaker from Democratic United Party, attended a closed-door intelligence session by National Intelligence Service (NIS), which is equivalent to the CIA in the U.S. "Ri attended Geumsung's Second Middle School before going to China to study singing," Jung said.
