In 2011, Jones made her theatrical debut playing the princess Young Fiona in the original production of Shrek the Musical at the Theatre Royal, Drury Lane.^[4][9] In 2013, she appeared in Rebecca Lenkiewicz's stage adaptation of Henry James's The Turn of the Screw as nine-year-old Flora, alternating between two other girls each night.
