Prince George was up to some hijinks at the palace!

The little Brit was with his family on the balcony at Buckingham
Palace for Trooping the Colour on Saturday, where he got adorably silenced!

His cousin Savannah Phillips playfully covered his mouth,
and he can be seen grinning during the service.

The tots were also seen making silly faces and clapping
their hands gleefully alongside Princess Charlotte as the watched the event,
which celebrates Queen Elizabeth’s 92nd birthday, though her actual
birthday falls in April.

The event also marked a big occasion for the Duchess of
Sussex, who made her Buckingham Palace debut alongside new husband Prince
Harry.

Meghan looked stunning a pastel dress and matching
fascinator, but her off-the-shoulder look actually broke some royal protocol
due to its daring shoulder-baring neckline.

Kate Middleton looked lovely in a pastel blue dress and
flowery fascinator which looked color-coordinated with the Queen’s blue look.

The royals always know how to show up in style!
