Chris - who is married to Oscar-winning actress Gwyneth Paltrow - said: "We're from very different backgrounds. But we love the same stuff everyone else loves. I love his music, and he's a super-cool guy, and he's genuine. I respect his decisions, and we have the same feelings about trying to be true in your art. It just happens that One Of Us is a nerd and the other is the coolest multi-entrepreneur on the planet.
"I think more people wonder why he's friends with me. Of course, I want to be friends with Jay-Z - he's cool as f**k. In Britain, they're like, 'How are you friends with Jay-Z?' It's almost like they're jealous. It's the same with my wife, 'How the f**k did you manage to do that?' And my answer is, 'I have no idea.' "
However, Chris says one thing they do have in Common is sport and Jay-Z has been teaching him how to play American football.
The British rocker added in an interview with Pitchfork.com: "We do play touch football. He's very good at American football - not only does he have all these other talents, but he can throw a perfect spiral. And then, on the other end, it smacks me in the head. In England, no one teaches you how to throw a spiral, so mine looks like an egg slowly limping through the air."
