SPIED! JAY-Z RIDES TRAIN TO PERFORM AT LONDON CONCERT

Once upon a time, a certain Sean Corey Carter better known as Jay Z could not tell an inquisitive journalist how much a train ride costs in the US. 

So its shockingly reassuring to spy the hip hop mogul hitching a ride on the famous London tube on Saturday night to the O2 for his Magna Carta Holy Grail world tour gig. 

Accompanied by Chris Martin and Timbaland, the rap icon mingled and bantered with fans - one of whom tweeted these candid shots.

Twitter user aminott4 excitedly shared the news on his feed, writing: ‘Casually getting on a train with Jay Z, Chris Martin, and Timbaland,’ along with a picture of the trio mixing in with the crowds.

AlwaysRocNation posted: ‘Jay Z, Chris Martin and Timbaland took the tube to the O2 Arena tonight!’, while Maverick_AC said: ‘It’s cool when JAY Z, Chris Martin and Timbaland get on the tube at Waterloo for tonights o2 gig.’

Well, join the club, Jay-Z's protegee Rihanna is a regular on London trains as well as the prime minister David Cameron. *The Spy ALWAYS finds out and ALWAYS tells it like it is. Follow @africncelebspy on twitter and like me on facebook or else....
