She was never fully offered the roll, but she was offered an audition. she turned down the AUDITION,, and though stephanie meyer wanted her to play bella, she was too tired and doesnt like working on projects back-to-back and because she was tired, she figured she wouldn't be able to do a very good job pagganap wise.
butanyway, DON'T U THINK THAT EMILY WOULD BE THE PERFECT ACTRESS TO PLAY RENESME CULLEN AS 17 ? III DDDDOOOO!!!!! (U CAN SO C EMILY WITH TAYLOR JUST SAYIN')
Stephenie Meyer thought of her, and I think she was offered the chance to audition for the role, but she didn't want to get involved in doing another project right after another, so she never auditioned. I bet she would have been good though!
