Rob with Edward's Long Timeless Hair

From Catherine Hardwicke's Director's Notebook

This twitter pic of Rob sporting a long hair raises questions if he was wearing the extensions sewn in for Catherine Hardwicke's attempt for Edward to have "long timeless hair". As Catherine said he hated it and from this picture, he looks pretty upset by it to put on a beanie- but then again he loves his beanies. What do you think?
