Nicole sacrificed forward and peripheral vision in the name of privacy walking with a friend in LA this week. She must be on her way to NYC, however, as she is a guest on tonight's Late Show With David Letterman. She was scheduled to appear with Paris in order to help promote The Simple Life Goes to Camp, but unfortunately Paris won't be able to make it. I wonder how many mentions of jail Dave will work into the interview and whether the famously sarcastic Nicole will take a few jabs at her locked up "friend" while on air? Yeah, probably.
