Flamboyant former NBA star Dennis Rodman's colourful tweets from the heart of Stalinist North Korea appear to have upset South Korea's best known cultural export, the "Gangnam Style" rapper Psy.
In one of several tweets since he arrived in Pyongyang on Tuesday with members of the Harlem Globetrotters, the retired basketball Hall of Famer wondered if he might meet up with Psy during his stay in the North.
"Maybe I'll run into the Gangnam Style dude while I'm here," he tweeted.
Whether Rodman was joking or not, Psy clearly decided he needed to be set right on the geo-politics of the divided Korean peninsula, and which side he hailed from.
"@dennisrodman I'm from #SOUTH man!!!" the singer retorted on his twitter feed Wednesday.
Psy, who has been on a constant world tour since his Gangnam Style video became the viral hit of 2012, was in his home country on Monday performing at the inauguration of South Korea's new president Park Geun-Hye.
South and North Korea remain technically at war after the 1950-53 Korean conflict concluded with a ceasefire rather than a peace treaty.
Inter Korean tensions are running particularly high at the moment, after the North conducted its third nuclear test earlier this month, triggering global condemnation.
