Kristen Stewart has admitted she feels pressure from 'Twilight Saga' fans to get her character right.

The 20-year-old actress - who plays Bella Swan in the movie series opposite rumoured boyfriend Robert Pattinson as vampire Edward Cullen - admits she worries about what people think of her interpretation of the much loved character, who first appeared in Stephenie Meyer's books of the same name.

She said: "It's just surreal to be a crucial part of a machine like this. I'm sort of the vessel. These girls are obsessed with Edward through me. If I wasn't right I'd be persecuted and put on a cross."

However, the actress revealed that she loves her character and can't wait to film the last two movies in the series, which are based on the final book 'Breaking Dawn'.

She said: "I'm excited to go and do the next couple of years of Bella's life."

The US-born beauty also explained that was excited to make upcoming movie 'The Runaways' - a biopic about rocker Joan Jett in which she stars alongside Dakota Fanning - and rushed to make it between 'Twilight' movies.

She said: "It was tough because I only had a really tiny window of free time, but I really wanted to make the movie. And I didn't want to get any older than Joan was when she was in The Runaways. I just crammed it in and hoped it would work."
