Madonna had a concert in New York City and a special guest stopped by.

Madonna started to perform her new song "Give it to Me" some concert listeners heard the beat to Gangnam Style in the background. Most people probably didnt think anything of it. Until PSY himself takes the stage to perform along Madonna. The 20,000 people that attended the concert were shocked to say the least.

PSY had actually flown in from Germany that day just so he could perform with Madonna. Is it just me or did Madonna's song actually go with Gangnam Style? Maybe she should keep it that way.
