One of the most famous people in the world.
Of course he needs more privacy than most people. I think like a couple of hundred people in the world know who I am, perhaps 1,000 max. This guy is known by something like a billion people around the world. Out of that number, a fair few probably want to meet / criticise / friend / kill him, so it's understandable he wants a bit of privacy. I think Joss Stone probably wants more privacy too, and deserves it.
Personally, I'd never want to be famous. What a curse.
Oh, vvv ... there's the downvote button, for anyone struggling to find it.
