Royal Family Is Reportedly Coming To America

Rumor currently has it that William and Kate might have a little vacation with the kids in Long Island, New York, according to a report from OK! Magazine. Part of this is due to strong words of wisdom that William's late mother, Princess Diana, supposedly told him when he was younger.

"Diana used to sit down with William and show him photographs of her travels, and she'd point out the exotic places she went on maps," a source said. "She'd tell him that he should never settle for a life inside the palace walls, and that he must experience all that the world has to offer."
