Marvin, a beloved pet, now lives at Adelaide Cottage and has quickly become a favourite of Princess Charlotte. Marvin shares his space with the one-year-old Princess, who loves to play with his whiskers, making him a beloved member of the family. Catherine shared the exciting news while unveiling the new magical garden at Hampton Court Palace.

Despite the clear skies, she opted to wear a recycled grey Michael Kors coat that she has worn on previous royal occasions. The magical garden, inspired by the myths and legends of Chuda, is located in the palace's old sloping courtyard. The renovation took six years. Catherine toured various sites, including some of the city walls and the Dragon’s Lair, while children played on the dragon slide and sandcastle area designed by award-winning landscape architect Robert Myers.

Her day continued as guest of honour at a luncheon promoting a new children’s mental health facility. She removed her coat to reveal a knee-length grey dress by Serbian designer Ana Ljubinkovic, which she has worn on royal tours. Held at Spencer House, a private London palace leased by Lord Rothschild, the luncheon highlighted the establishment of a centre focused on children’s mental health.

Catherine met with key donors and families who have benefited from the centre’s services, highlighting the need for early intervention in mental health, with the aim of raising £34 million for the initiative. The project will combine research, teaching and a range of support services for children and families struggling with mental health issues. The PE Foundation recently pledged £2 million to this important cause.

Catherine also met families like Vicky F and her daughter M, who have made great strides since joining the programme. To round off her day, Catherine visited the National Portrait Gallery, where she saw two portraits of herself featured in the 100th anniversary edition of British Vogue. With a dedication to both public and family duties, the Princess of Wales has always maintained a balance between tradition and modernity, showcasing the intimate side of royal life.
