Princess Catherine of Wales made her first significant royal appearance on November 9 at the Festival of Remembrance concert held at the Royal Albert Hall in London. Accompanied by Prince William, she smiled and applauded during the musical tribute honoring fallen British soldiers. This event comes after both she and King Charles III have recently returned to public life following cancer diagnoses and treatment. Princess Catherine completed her chemotherapy in September and is eager to take on more royal duties, while King Charles is also managing his health while fulfilling select engagements.
