Not much is known about her early life. All we know, she hails from France and she is raised there. She has a fashion-designing cousin named Julie, who she is really close to. Growing up, she continues her studies in journalism at Mouseford Academy along with her four new friends; Nicky, Pamela, Violet, and Paulina.
