If you don't watch Game of Thrones, Arya Stark, played by 19-year-old Maisie Williams, is one of the youngest and most badass characters.
She's using her fame to support good causes - including raising money for the NSPCC.
Williams wasn't impressed with the Mail Online's write up of the event, however.
