When Jay Z was getting ready to do his very first show at a brand spankin’ new Barclay’s center last year, he did something we can assume he hasn’t done in years (or at least since they started making Maybachs): he rode the New York Subway. Continuing in his tradition of taking public transportation despite his enormous fame, Hov hopped on the London Underground (the British equivalent of the subway) to commute to the 02 Arena for his Magna Carter World Tour this past weekend. This time he brought along a heap of his famous friends including super producer Timbaland, Coldplay front man Chris Martin and New York Yankees ace CC Sabathia. Check out video and photos of the ensuing madness below.
