The five-member girl group performed their hits "Bad Boy" and "Red Flavor" in front of North Korean citizens.
Kim Kong Un was "deeply moved" by Kpop group Red Velvet's performance in Pyongyang.
After the performance, the rogue nation's leader personally went backstage to shake the hands of the group and take photos with them.
The performance coincided with the beginning of annual joint South Korean-U.S. military drills, which have previously been met with denunciations and missile launches by the North. He was also seen talking to members of Red Velvet, who have more than 4.6 million followers on Instagram.

The concert at the elaborately decorated 1,500-seat East Pyongyang Grand Theatre ended with a standing ovation by the packed audience after a finale featuring all the stars singing a song about unification.
When K-Pop boy band Shinhwa performed in North Korea in 2003 as part of a similar cultural diplomacy venture, the audience - dressed in suits and traditional dresses - greeted them with silence and stony stares. The discussions and the speculations were going on that whether and how would he meet the US President, then come the first ever foreign visit of the North Korean leader.
The Day of the Sun falls on April 15, when North Korean founder Kim Il Sung, Kim Jong-un's grandfather, was born in 1912.
Kim had been planning to attend the Tuesday performance but chose to watch Sunday's show due to "political schedules", KCNA and South Korean officials there said.
