Madonna surprised her fans at her New York City concert by unleashing a trotting Psy and his Gangnam Style on them. The popstar welcomed the galloping Korean sensation on the stage for a joint performance at Madison Square Garden to the delight of her audience.

Madonna started singing the song solo at first and then the Korean sensation suddenly appeared on stage from underneath. “He flew all the way from Frankfurt, Germany, this morning just to cheer your asses up!” explained Madge, gushing later, “I’m a very big fan of yours. I’ve never been to Korea—hope to come there one day.”
