The gardens of Buckingham Palace were transformed into a giant playground on Saturday, for a tea party hosted by the Duke and Duchess of Cambridge and Prince Harry.
Some 850 young people were invited to join the royal trio for an all-out 'Party at the Palace'.
The special event was held for the children of those who have died in military service to their country.
The fun-filled day included water balloons, face painting, cupcake decorating, magic tricks and the RAF Falcons parachuting onto the palace lawns.
Below we see a playful Kate aiming for William with a water cannon.
The Duchess looked radiant in the Spring sunshine, wearing her cream See by Chloé Lacy Jersey Long Sleeve Dress. The frock is currently available at Saks Fifth Avenue.
Many will recall that Kate premiered the French label frock at a children's garden party during her trip to Canada last Fall.
She again accessorized with her cream ACNE STUDIOS 'Orione' waist belt and taupe Monsoon 'Fleur' Suede Espadrille Wedges.
Monsoon has reissued the 'Fleur' wedge pumps this season in linen and navy suede.
The Duchess finished the look with with her Annoushka pearl/Kiki hoop earrings.
Just a reminder that this time next week, we'll see Kate, William and the kids at Pippa's wedding!
