Jay-Z recently revealed in an interview that once, when he called President Barak Obama, the chief executive had his album The Blueprint 3 on in the background.  Well, we figure that's what might have been bumping on the stereo Wednesday when Hova made his first visit to the White House. 

The Washington Post reports that at the end of his concert in Washington, D.C. on Wednesday, Jay announced from the stage, "I just came from the White House," and officials later confirmed that Jigga had, indeed, dropped by 1600 Pennsylvania Avenue.  Apparently, he got a tour, and then had a brief, unscheduled visit with President Obama.
