North Korean state television has confirmed that leader Kim Jong Un is married and named his wife as Ri Sol Ju.
The television reported that Kim and Ri, whom it described as his wife, took part in a ceremony marking completion of a Pyongyang amusement park.
South Korea's Unification Ministry said it appeared that Ri was the woman who has been pictured several times at Kim's side at public events in recent weeks.
Photos and film footage of the smartly dressed woman in her 20s had sparked speculation as to her identity.
Kim, believed to be aged in his late 20s, took over the nuclear-armed nation when his father Kim Jong Il died last December.
But the secretive state had previously released no details of his private life.
