Britain's Duchess of Cambridge will temporarily swap royal duties for an editor's chair to raise awareness of children's mental-health issues.
Kensington Palace says Kate will guest-edit The Huffington Post news website for a day next month, focusing on articles related to childhood mental illness.
The 34-year-old, who is married to Prince William, is patron of several children's charities.
The palace said Friday that Kate "has made the mental health of young children a key focus of her work in recent years. She is delighted that The Huffington Post will help put a spotlight on this important issue."
Huffington Post U.K. editor Stephen Hull said staff were thrilled to welcome the duchess.
Kate's sister, Pippa Middleton, has also tried her hand at journalism, writing articles for Vanity Fair and The Spectator.
