Who is She?

Who is she? On October 15, 2008 this woman was taped by a small army of videographers surrounded by an entourage of assistants. Here's what we know: the place was Colonial Williamsburg, Virginia; the time was around 5 pm. The woman at the center of attention didn't say much but danced around and smiled a lot. Some people have guessed that she is a singer or an actress. Really? If you know who she is send me a message in the comment section. Know that.
