I'm pretty sure I remember reading something where she said she likes Estee Lauder Private Collection- Tuberose Gardenia. I also have it my head that she likes Fracas, I think that came from a thread here on The Ledge.
When I met her for the DVD signing she smelled like she was wearing a fragrance that was light and powdery, like old fashioned dusting powder.
Powder, heh.
