Video: Madonna Does "Gangnam Style" In Concert with PSY

"Vogue" master Madonna struck a different kind of pose last night during her concert in NYC -- by going "Gangnam Style" with PSY!

The Queen of Pop performed at Madison Square Garden on Tuesday night and while her tour has been a largely guest-free zone so far, the Korean singer surprised the crowd to perform his insanely popular song.

Madge is definitely the biggest celeb so far to attempt PSY's fancy ride-the-pony footwork, following stars like Britney Spears, Andrew Garfield, Brad Paisley and Carrie Underwood, the cast of "Dancing with the Stars" and Vinny from "Jersey Shore."

So ... how'd she do? Check out the video above to see the 54-year-old singer tackle PSY's moves.
