Prince William Drives Prince Harry and Family to Buckingham Place for Pre-Christmas Lunch

Queen Elizabeth II hosts the annual lunch for members of the royal family.

Prince William, 34, was photographed behind the wheel driving his family, including Princess Kate, to see "Gan Gan," as William and Kate's 3-year-old son, Prince George, calls his great-grandmother, Queen Elizabeth.

The Middletons have attended church and Boxing Day festivities with the royal family in the past, but this will be their first chance to spend Christmas at their Bucklebury estate with George and 19-month-old Princess Charlotte.

"The Duke said they were all really excited about Christmas and that George is already opening his presents," King said. "He thought it was quite funny. That's kids for you, even the ones that are princes."
