I think that you're always at least 100 feet from a Starbucks, no matter where you are in the world.. I read that somewhere. Or maybe I made that up. Who cares, there's a ton of Starbucks around.. I mean, there's one in the middle of the frikkin forbidden city in Beijing so that when the Emperor wants his frappucino, he doesn't have to go far.
So as far as celebrities go, they seem to love the Starbucks more than anyone.. Yah, they love their coffee.
