I hadn't heard that he wasn't nice anymore. I would guess that fame has changed him; he obviously knows what he's got and uses it to his advantage. Who wouldn't. He probably still is nice but, you more than likely don't see it truely unless you are in his inner circle. Of course, the pics I have seen of him with fans he doesn't seem crabby or irritated. Maybe just hurried, he seems to stretch himself kinda thin at times. Just an uneducated guess on my part.
