Kristen Stewart isn't interested in vampires.

The 'Twilight' actress — who plays Bella Swann, the human love interest of Robert Pattinson's vampire Edward Cullen in the film franchise — insists she was more attracted to the relationship element of the franchise than the supernatural beings.

She said: "It wasn't the vampire aspect of the story that has ever drawn me to it, it's Edward's fight with his human side and how much he hated himself and was ashamed of himself.

"The vampire element was just representative of everybody's normal human problems."

Kristen recently admitted she has deliberately taken on different movie roles in between working on the 'Twilight' franchise because she worried the series would turn her into a "psychopath".

The 'Adventureland' actress said: "I think I would have been a psychopath by the end of a four-year stint on the 'Twilight' saga without anything like 'The Runaways' to change it up."
