The 21-year-old-actress plays Bella Swan in the `Twilight: Saga` movies and she can understand why her character would fall in love with blood-sucker Edward Cullen - who is portrayed by her real-life boyfriend Robert Pattinson in the film series.
She said: "Vampires are very sexy. I think it`s because they`re meant to draw you in just to the point where they can then kill you. It`s like a forbidden fruit. If it`s something you can`t have, then naturally you just want it more. Maybe that`s why I was drawn to the role of Bella in `Twilight`."
Although she can recognise the erotic qualities of the mythical creatures, Kristen wouldn`t be happy to be confronted by a vampire in real life.
She added: "I wouldn`t like to be confronted by a real vampire, though, as they can read your mind!"
