Kate Middleton and Prince William have finally introduced Prince George to the woman who someday will make him very rich and powerful: His great-grandma, Queen Elizabeth. Gee, I hope they got along or who knows if the Queen might rewrite the rules and leave it all to Harry! Haha. JOKE. No worries, Georgie. Anyway, the royal pair are vacationing with the Queen at Balmoral Castle, in Aberdeenshire, Scotland. Prince George must have passed muster because a photo of Kate and Wills with the baby took front and center on the Queen's table in one of the castle's sitting rooms. But the castle is also a popular tourist destination -- and you can stay on the estate grounds. Maybe Kate and Will will invite you over for tea! Here's a look at Balmoral Castle.
