Britain's Queen Elizabeth II traditionally celebrates her official birthday with an annual Trooping the Colour military parade, which members of the royal family take part in. Some, like Princes William and Charles, take part in the parade in military uniform, others following in carriages. It always culminates in the royals gathering on the Buckingham Palace balcony as a RAF flypast goes by overhead.
This year it was undoubtedly the Prince Louis show. Here are six cute moments you may have missed from the royal day out ...
1. It was the Prince Louis show
The royal tot this year made his Buckingham Palace balcony debut. However, he didn't look delighted to be there.
The little one did seem to brighten up when the flypast flew overhead.
The one-year-old was certainly centre of his parents' attention...
2. Prince Louis mirroring Prince Harry's style
Prince Louis wore a cute little blue and white outfit, which eagle-eyed fans noticed was very similar, if not the exact same, as an outfit Prince Harry wore to the Trooping The Colour parade in 1986.
Like the Duchess of Cambridge, his aunt, Princess Anne, wore a yellow outfit.
3. Meghan's new ring
The Duchess of Sussex was seen for the first time since welcoming baby boy Archie Harrison in May. The duchess wore Givenchy for the parade, but it was her ring finger that got the most attention. She was wearing a third ring which royal watchers have speculated may have been a "push present" from Prince Harry, or an eternity ring.

4. George's sneak peek out of the window
Prince George taking a look at the crowd out of the Buckingham Palace windows has become something of a tradition for the young prince.

5. Kate and Meghan having a laugh
The Duchesses of Sussex and Cambridge seemed to share a joke as they made their way to Buckingham Palace. They were joined in their carriage by the Duchess of Cornwall and Prince Harry. Interestingly, the Duchesses of Cornwall and Cambridge have shared a carriage annually since Kate joined the royal family in 2011.
