Dawna Lee Heising has been crowned Ms. US World 2007. Now if you look at her perfect body dressed in what I think is way too tiny thong (reminds me of the one the SnakeBabe wore), you might think she is bimbo. How wrong are you? She is a big kahuna at high-tech company and has an MBA and a Ph.D. Talk about beauty and brains combo. No wonder then that she has acted in film, television, and theatre productions. She has also worked as a professional model.
