Duchess Kate Visits Children's Playground

The duchess is on royal duties after her British Vogue cover was revealed.

The Duchess of Cambridge, 34, has a busy day ahead focusing on some of her patronages. Her first stop was Hampton Court Palace, where she opened Magic Garden, a new children's playground area.

Kate also told school children that, in addition to their beloved cocker spaniel, Lupo, the royals also have a pet hamster named Marvin at home, according to ABC News' royal contributor Victoria Murphy.

Today, Kate will end her day with a visit to the National Portrait Gallery where she will view two of the photos in the "Vogue 100: A Century of Style" exhibition. Kate, an art enthusiast and avid photographer, is Charitable Patron of the National Portrait Gallery and does what she can to raise the profile of the museum, located in London's Trafalgar Square.

Kate was photographed by British photographer Josh Olins for the cover of British Vogue to celebrate the magazine's 100th anniversary, in a collaboration with the National Portrait Gallery.

For the magazine, available on newsstands June 5, the duchess was photographed in the Norfolk countryside. British Vogue editor-in-chief Alexander Shulman said the photos captured Kate's great sense of humor.

Even the family's dog, Lupo, made a guest appearance in the photos. Kate is said to have wanted the look to be "informal" and to depict her "countryside" roots.

"She didn’t want to be dressed as a fashion plate and was not keen to be shot in gala gowns and tiaras," reads a description in the magazine's June issue.

In five new photos, Kate can be seen in a plaid shirt by Cabbages and Roses and in a retro jean overalls ensemble by AG Jeans and a red turtleneck. Perhaps most stunning is Duchess Kate casually chic dressed in a lovely, long leather coat as she sits atop a bicycle.

British Vogue's Shulman wrote of Kate in the June issue, "We drank coffee and everyone prepped until the duchess arrived, in jeans and a parka, her hair in big rollers, with a bright, inclusive smile."

"She walked through the small cottage door with her hairdresser, Amanda Tucker, who was dragging a wheelie case of products," Shulman wrote. "The duchess joked about how she must have appeared to anyone who saw her driving the car in her rollers, before introducing herself to everyone she hadn’t yet met."

British Vogue editors said Kate came ready to work with an utter "lack of vanity." The shoot, which took place in the frigid, biting cold, had Kate allowing the stylists latitude to do as they wished, all without complaint.
