The only daughter of Alphonse James de Rothschild III, and future Baroness of one of the wealthiest noble families in Europe, she grew up to study the History of Art at University. It was from there she went into the world of acting, taking a course in theatre.
She enjoyed her first taste of international box office success in the mid-1990s but is still an actress mostly unknown outside of her native France. Her insistence on working exclusively in movies filmed in France is maybe due to the poor health of her mother the Baroness Alexandria Rothschild. She has acted alongside such stars as Gwyneth Paltrow and Alice Evans.
She married American economist and businessman Fatafehi Tupoumalohi in 1999.
