Yesterday I told you about Madonna's sultry version of her hit Like a Virgin while in concert this week in NYC.  Well, turns out that's not the only surprise she had for her fans.  South Korean superstar Psy joined Madonna onstage for a surprise Gangnam Style interlude, complete with Madonna and dancers galloping in the background.  I would have LOVED to see just this portion of the show – I can't help it, I love me some Gangnam Style!

PSY's wildly popular viral hit “Gangnam Style” is about Korea's glitziest district, so it only makes sense that the world's most famous “Material Girl” would approve–right?

Right! Madonna proved she is indeed a fan, by bringing the South Korean rapper up on stage with her Tuesday night in New York City. Read more and watch performance here.
