On Thursday evening, the royal mum opened up Kensington Palace to aid ambassadors and Rio Olympic hopefuls, for a banquet dinner to support one of her charities, SportsAid.
The brunette beauty, who hosted the event solo, donned a stunning $4,090 floor-length gown by Roland Mouret.
The royal blue masterpiece featured cold-shoulder cut-outs and a geometric neckline, that perfectly steered the eye up to the bedazzled hoop earrings that hung delicately from inside her famous Chelsea blowdry.
The Duchess proved that diamonds are indeed a girl’s best friend with the Cartier diamond ‘Trinity de Cartier’ earrings in 18-karat gold worth over a whopping $76,000.
After posing for pictures and greeting guests in the picturesque gardens of the lavish palace, the mother of George, two, and Charlotte, one, led attendees into the King’s Gallery for dinner.
Guests were treated to a delicious meal beginning with English asparagus and truffled potato alioli, while main course consisted of seared fillet of beef with dauphionoise potatoes in a beef jus.
For dessert, the Duchess, charity ambassadors and young athletes indulged in orange and Valrhona chocolate bar with milk chocolate mousse, orange jam and an almond praline ice cream, but before they could satisfy their sweet tooth’s, the 34-year-old had some kind words to say.
“Some of you may know that I love sport. I love cheering on teams and athletes that I am passionate about,” she began.
“I love the physical challenge sport presents and the mental strength it gives us all. And I love the way it so often brings people together to work as part of a team.”
Expressing her excitement for the 2016 Rio Olympic games, the mother-of-two quipped, “We cannot wait to meet the next SportsAid champions – the next Chris Hoys and Katherine Graingers who will remind us all of the magic and the power of sport.”
“So thank you all for supporting the incredible work of SportsAid. I am immensely proud to be their Patron and I can’t wait to cheer on our team competing in Rio”
And as the night came to a close, it would be safe to assume Kate set aside some time to put her feet up before one of her busiest weekends this year kicks off.
The Queen’s official 90th birthday celebrations begin this Friday with a Service of Thanksgiving at St. Paul’s Cathedral.
And from then on, the celebrations will only kick up a notch with the annual Trooping The Colour ceremony set to take place in London – where little Princess Charlotte is expected to make her balcony debut.
