The royals met several celebrities from Commonwealth countries including Strictly judges Craig Revel Horwood and Motsi Mabuse , who hail from Australia and South Africa respectively, as well as Jamaican singer and actress Grace Jones.
Charles and Sophie have a close relationship, however, this marked the pair's first official joint engagement since the monarch hosted the Emperor and Empress of Japan back in June.

Grace and the King
Among the people the King met was singer and actress Grace Jones, who the monarch managed to make giggle. Speaking after the event, the A View to a Kill star said: "I have met them a few times, ever since James Bond. I also did the hula hoop for the Queen at the Jubilee.
"So we have a history. Being Jamaican, I believe that the Commonwealth has positives. It’s a very good thing that brings people together in a positive way."

Strictly speaking
Charles and Strictly judge Craig Revel Horwood had a good laugh at the event, although Craig revealed he didn't think the monarch would be tuning into Strictly Come Dancing at the weekends.
Telling the royal that he was bringing out his own album, Craig later told media: "I think he would prefer to listen to an album than Strictly. The Queen loves Strictly, not sure the King is such a fan. I know the Queen absolutely adores it."

An impressive display
Charles was treated to an impressive dance by former rugby player Freddie Tuilagi. The 53-year-old, who was acting as an honorary consul from Samoa gave a traditional Siva Samoa dance, with the monarch even getting involved!
After the event, Freddie joked: "The King is going to Samoa and so we gave him a bit of a taste of Samoa man, dancing, man. I said to King I'm going to do it for you when you get to Samoa you experience it. He said he loved it, he loved it. They were good moves, he had good moves."

I'm sorry, I really did try but I fail to see the excitement about Chuck, Cowmilla and Sophie getting together. Talk about thoroughly boring and yawn inducing. Grace Jones is cool though. 🥱😴💤
