Psy & Madonna in 'Gangnam' mash-up at NYC

Lately, Madonna's not been one to pass up a chance to try and stay/be relevant by jumping on a bandwagon rather than inventing the wheels for it.

But she gave fans at her recent homecoming concert in New York City a little something extra special for still believing in her—a surprise, surprise live collaboration with Korean superstar Psy!
The duo teamed up to perform a mash-up of Madonna's Give It To Me and Psy'sGangnam Style, which sent a packed Madison Square Garden completely bonkers.

After the show, Psy uploaded a photo and a clip of their performance onto his Twitter account, mentioning that Madonna displayed real "classy stage manners".
