Having already revealed that Chris Martin and Timbaland would be joining Jay-Z on stage to perform 'Ain't No Love (In the Heart of the City)', it seems that they all decided to travel to the O2 Arena together as well.
The group were spotted leaving Waterloo Train Station and entering the Underground in order to make their way to another sold-out night of Jay-Z's Magna Carta Holy Grail UK tour.
Of course, the internet completely blew up after the sightings, with fans taking to Twitter and Instagram to let the world know that hip-hop royalty was taking the Tube.
