Bell stated she never thought of herself as womanly because "I always play and look and act 10 years younger than I am." However, she said, "Something magical happened when I turned 25—I looked in the mirror and was like, 'You might not get carded for an R-rated movie anymore.' Like I didn't have a little stick figure anymore." Bell has said that many of her characters are tomboys because she was "not homely enough to play the nerdy girl and not nearly pretty enough to play the pretty girl".
