Kristen Stewart was on the Late Show with David Letterman last night promoting Twilight.  Normally celebs arrive in casual clothes and then change at the studios, but she went on David Letterman in jeans and is shown in a dress.  I know it’s early and, as always, I’m sleep deprived, but this is really screwing with my brains.  Sad, right?  It doesn’t take much by the time Friday rolls around.

Twilight opens today.  Will you be going, or will you wait for the crowds to die down?
