The 22-year-old, who recently rekindled her romance with Robert Pattinson, said she did not find it difficult to play a young mother, reported Hollywood life.
"It was one thing about the story, (playing a young mother), that was never difficult for me to grasp or relate to. Everyone thinks that it's so peculiar to play such a young mother. It's really not.
"I think you're either born with that or you're not. That was one thing that both me and Stephenie were so protective about. It was a fun thing to play," she said.
The last film in the series will hit the theatres on November 16.
