Jay-Z and Alicia Keys rocked the Yankee's stadium in New York Thursday evening when they performed for Game 2 of the World Series between the New York Yankees and the Philadelphia Phillies.
Jay-Z and Keys performed their hit song Empire State of Mind, he dressed in a Yankees cap and jacket and her playing the piano and singing the chorus.
I made the Yankee hat more famous than a Yankee can, Jay-Z sang as the crowd roared.
The Yankees however didn't seem so excited, but cameras caught some of the players recording the show and bobbing their heads.
