Weird topic - I know.
5. Piper Fawn/Faith Lightspeed/Ariel - Beautiful redhead model. Does mostly erotica.
4. Sasha Grey - porn actress (finished her carrer recently). She was one of the most hardcore porn actresses, yet she was very inteligent, interested in art, psychology. Extremely interesting character.
3. Emma Watson - I don't have to tell you who she is. The star of Harry Potter movies, grew up into a sexy woman and what's the most important - she doesn't act as a celebrity. She's still a normal person - respect.
2. Kaya Scoldelario - star of Skins (UK) series. Played Effy Stonem (without any actor experience), one of the most amazing characters in movies I've seen.
1. The one you love - you know the best, who she is :) She outshines all the woman above by miles, even if she isn't as beautiful or famous.
