Margaret "Peggy Dupree" Warburton is one of Tess's friends at Camp Rock, who is bossed around. Just before her, Ella and Tess were supposed to perform together, Tess yelled at them and she stood up to her, telling her what she tought of her. It isn't until the end of the movie that she performs her song "Here I Am" that she reveals her real name, and her talent. Though Peggy is a short form of Margaret, it's not known why she also changed her surname.
