Earlier today, Jay-Z appeared at a press conference at the Plaza Hotel to promote the new DJ Hero game. While he was there, he confirmed to MTV that he and Alicia Keys will be performing their smash single "Empire State of Mind" before the first pitch is thrown. This is oh so appropriate, and definitely gives us another reason to watch the game! Check out the video interview below. Think he'll get booed when he says "I made the Yankee hat more famous than a Yankee can"? You know the Yankee fans don't play.
