Kate Middleton Looks Pretty in Pink at a Garden Party With Prince William and the Queen

It's shaping up to be a busy week for Kate Middleton and Prince William! After the duchess 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. The Duke of Cambridge sported a top hat and tails for the affair, while Kate looked pretty in an all-pink ensemble.

Sadly, Will and Kate 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?
