Jay Z sent London tube riders into a frenzy after he randomly rode the public transportation alongside Timbaland and Coldplay frontman Chris Martin. The "Magna Carta Holy Grail" rapper was on his way to the O2 Arena for his sold-out show on Saturday night, and the close pals surely turned heads among the other passengers.

This isn't the first time Jay Z has ridden the train to one of his shows. Last year, he famously rode the subway to his Barclays Center show. In both instances he's been open to talk to fans and just be "normal" for the day.
