JLD has a pronounced accent on words like "downtown". It comes out as "daowntown" She did it tonight on "now" which became "naow", which reminded me of this. As near as I can tell she grew up in the Washington DC, NYC area. Is this a common accent for that part of the country? I'm not aware of any other strangeness. Seinfeld is from LonG Island, which is the same general area and he doesn't have this trait.
While digging through her biography, I found her father is not a millionaire, as I had always thought. He is a billionaire.
