The Duke and Duchess of Cambridge showed off their artistic skills during a visit to the Inner City Arts campus in LA today. William and Kate met with a group of children to paint and made their mark with a hand print mold. Kate Middleton and Prince William started their day with Reese Witherspoon at a private reception in support of Tusk's USA charity, and they will soon head to a Service Nation: Mission Serve event. Today's stops mark Kate and Will's final appearances on their California tour before they head home to the UK. It's been a busy month for the duo, who started off in Canada, and there are so many great pictures of Kate Middleton and Prince William during the Canada leg of their North American visit.
