Today, the Duke and Duchess of Cambridge along with Prince George enjoyed a day out at the Royal International Air Tattoo in Gloucestershire.
This is the first time the little Prince has accompanied his parents on an official engagement in UK.
The air show at RAF Fairford is the largest event of its kind in the world. There was also a celebration to mark 75th anniversary of RAF Air Cadets, of which Kate is Honorary Air Commandant.
Kate took over the role of patron from the Duke of Edinburgh in December of last year.
The Duchess wore her Lauren 18ct yellow gold pave diamond leaf earrings (£2,200) by Kiki McDonough.
