Irishman Eamonn Kilbride, a father of three, suffered a heart attack at a Christmas party in Burnley, England last Saturday and died while showing off his galloping Psy moves.
The tragedy was especially hard on his wife Julie, who was celebrating her birthday at the bash.
Acute heart failure has been listed as the official cause of death.
The news breaks a week after Psy was forced to apologise to US fans following the discovery of footage featuring the rapper making anti-American remarks at a rally in his native South Korea a decade ago.
