The couple has three children: George, Charlotte, and Louis.

As a working royal, Catherine undertakes extensive duties, with her charitable efforts primarily focused on early childhood development, addiction, and mental health, notably co-founding the "Heads Together" campaign in April 2016. In a significant personal update, she bravely announced in early 2024 that she was undergoing chemotherapy for cancer, resuming duties later that year. Her influential public image, dubbed the "Kate Middleton effect" on fashion, has garnered global attention, leading Time magazine to list her among the world's most influential people multiple times.
