Watch: Duchess Kate gave Buckingham Palace tourists the best surprise!

By Meaghan Wray

It was a lucky day for tourists stopping by Buckingham Palace earlier this week. While most royal fans typically come to admire the historic building, few anticipate actually catching a glimpse of one of the Royal Family’s most senior members. But lo and behold, the Duchess of Cambridge was spotted behind the wheel heading into the palace, perhaps to stop by for a visit with her grandmother-in-law, the Queen!

Given that the rear windows of her car are heavily tinted, it could be that Princess Charlotte and baby Prince Louis were in the backseat, about to enjoying a visit with their grandma. The three-year-old princess finished up her school year on Wednesday (Dec. 12), while Prince George’s last day is Thursday (Dec. 13). Prince William and Kate’s adorable kids have also been learning to swim at Her Majesty’s pool, which is often the reason for the royal mom’s visits.

One lucky girl from Hannover, Germany got the glimpse of a lifetime when Kate pulled through the palace gates, followed closely by what appeared to be a security car. In the video she posted to Instagram by melissagrflx, the duchess, wearing a pretty cream top, can be seen showing off her megawatt smile and waving at her excited fans, who definitely were not expecting to see her drive by! Melissa captioned the snap: “At Buckingham Palace.  When you're so lucky and get a shot of Kate Middleton right when she gets to the Palace. ”

She opened up to HELLO! about the experience, saying: "We went there without knowing that anything special would happen that day. There were many people waiting for the Changing of the Guards when she came to the palace. I really didn't expect to see her. It was a short but exciting moment."

Preparations are well underway at the Palace for the holiday season, as the Buckingham Palace Christmas trees have gone up and the family is preparing to head to Sandringham for their annual celebrations! The Cambridge family will be heading to the country alongside the Sussexes. It’s Duchess Meghan’s first Christmas as an official member of the firm, though she was on hand last year when she was newly engaged to Prince Harry, and it’s been reported that her mom, Doria Ragland, will also be there to ring in the festivities. It’s gearing up to be a very jolly Christmas this year, made even sweeter by the upcoming arrival of Baby Sussex this spring!
