The squad of around 100 young women did not know how to react when they came face-to-face with their leader’s doppelganger.
Some smiled nervously while others tried not to watch as the portly man in glasses, with slicked black hair and a long coat, strode in front of them.
The impersonator, who identified himself as an Australian musician with Chinese heritage named “Howard”, beamed as he waved a “united Korea” flag at the women.
After around ten seconds, they regained composure and started singing.
Two men in black jackets soon intervened to bundle “Howard” away to seats further down in the stadium.
He later said they were “p***** off North Korean” minders.
“Howard” continued to watch some more of the action at the women’s ice hockey match, where a united Korea team was playing Japan.
Asked how he was feeling, the impersonator said jokingly: “I’m feeling great – a little bit full, but I’m great.”
He later added: “I’m here to promote peace”.
“Howard” was later briefly detained by officials at the Pyeongchang Games, but posted a video of the ordeal on Facebook after.
He wrote of the North Korean cheerleaders: “Meeting them in the character of the Supreme Leader was quite a surprise for them and their reaction ranged from surprise, shock and even some mild giggling.”
