We rarely see Madonna share the stage with other pop stars during her major concerts. But her New York fans at the Madison Square Garden witnessed their idol sing and dance with Internet sensation Psy!
Psy flew all the way from Frankfurt, Germany to share the stage with the "Material Girl" and do the "Gangnam Style" with her.
Madonna said she was a big fan of Psy and liked the red suit he wore for the performance.
The K-Pop artist says this is definitely the highlight of his career so far.
