Popsugar Celebrity The Royals Kate Middleton and Prince William Palace Garden Party 2019 Kate Middleton Looks Pretty in Pink at a Garden Party With Prince William and the Queen 21 May 2019 by Monica Sisavat Solís Image Source: Getty / DOMINIC LIPINSKI It's shaping up to be a busy week for Duke and Duchess of Cambridge. After Catherine debuted her "Back to Nature" garden during London's Chelsea Flower Show and Will visited the River Thames, the royal couple attended Queen Elizabeth II's garden party at Buckingham Palace on Tuesday. Prince William sported a top hat and tails for the affair, while Kate looked pretty in an all-pink ensemble. Sadly, the Duke and Duchess left their kids — Prince George, Princess Charlotte, and Prince Louis — at home this time around, but they did share some adorable photos and videos over the weekend from their visit to the "Back to Nature" garden. In one of the clips, Will asked George to rate his mom's garden out of 10 (10 being the best), and the 5-year-old adorably gave it a 20! How sweet is that?
