I really miss the world before Twitter . . . when every single tiny little thought that popped into a celebrity's head wasn't treated as "news".

But we're through the looking glass on that, people, and there's no going back. So here's what some of the stars Tweeted about the 10th anniversary of the September 11th attacks . . .
