Tommy's girlfriend / 'West' cigarettes

Does anyone know who played Tommy's girlfriend, the one at the beginning of the movie? She never really shows her face, but much skin otherwise.

On a different note: Did anyone besides me notice how often the camera zooms in on "West" cigarettes throughout this movie? Was it officially sponsored by Reemtsma?

Edit: I just found out that there is a book by Kathrin Niederdorfer on product placement that mentions this movie. But I won't pay 17 Euros just to be allowed to read someone else's Bachelor Thesis.
