Jay-Z imagines his audience naked when he performs live.

The rapper - who headlined the main stage at Glastonbury festival last month - doesn't care how many people he plays in front of because they are all nude in his head.

He joked: "They're just people. Don't matter if it's 11 people or 11,000. I just imagine them naked."

Jay-Z - who is married to singer Beyonce - also revealed he was shocked by the size of the site for the Glastonbury music event.

He added to Britain's The Observer Music Monthly magazine: "What was breathtaking was the entrance to Glastonbury, when you come over the hill and you see those tents. I was actually in the bathroom of the bus at the time. Everyone was like, 'Oh my God! Come out! You've got to come out now!'"

"I was like, 'Wait a minute. This isn't a festival. This is a country! This is tent city.' That's when it stopped being just a concert."
