Jay-Z and Chris Martin might be global superstars with more money in the bank than they know what to do with but they proved how down-to-earth they are by surprising Tube passengers on Saturday night.
Heading to the O2 for Jay-Z's gig, which is part of his Magna Carta Holy Grail World Tour, they were spotted at Waterloo underground station waiting on the platform with fellow megastar Timbaland.

And while fans and Twitter users were surprised to see the music legends slumming it on public transport, they were even more shocked when they actually boarded the train and headed to North Greenwich for the O2.
They looked more than comfortable on the London Underground and laughed and joked with excited fans.
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.!'
Clearly in the giving mood, the night before they'd given fans a real treat as the Coldplay frontman joined his pal on stage.
They performed Ain't No Love (Heart Of The City) together, while Timbaland worked his magic at the back.
