The 21-year-old actress' character Bella Swan gives birth to a child with her vampire lover Edward Cullen – played by her real life boyfriend Robert Pattinson – in 'The Twilight Saga: Breaking Dawn' but Kristen doesn't think it "far-fetched" to think of someone so young as a parent.

She said: "I don't think it's far-fetched for someone of my age to be having a child. One of my best friends just had a baby and she's very, very, very, young. I definitely related to the maternal aspect of things very strongly."
Despite her maternal instincts being awoken during filming scenes for the series, she admits she was a little freaked out by the animatronic child, operated by a member of the crew, which she had to interact with in certain scenes.

She said: "Filming it, this guy's sweating under your eye line, they get the hand up to touch your face and then it sticks to your hair and pulls a little bit.

"You're like, 'Ugh! Get that thing off me. Get me a baby, this is ridiculous.' It had hair and it's a newborn baby!"
