She reportedly mingled with photographer Mary McCartney and Freud's daughter Bella during the visit.

The Duchess, who studied art history at St. Andrew's University, was recently named royal patron of the National Portrait Gallery.

Next week, she'll travel to Liverpool on Valentine's Day to visit an alcohol-free bar linked to one of her other charities, Action on Addiction, and will also visit Alder Hay Children's Hospital.

William left for his six-week deployment to the Falklands last week.
