Camilla revealed her friends and family all voted for her to win and revealed the Queen was also a fan of the show.
The Duchess said: “Rose, the Strictly star. I said we were all voting for Rose, I don’t know how you did all those dances.”
After the meet-and-greet, she said: ‘It was really funny because she’s a huge fan of Strictly Come Dancing and she mentioned that she voted for me, which is so lovely, and her grandchildren watch it.
“It is amazing, so lovely. I mean, come on, it’s the Royal Family voting for me, sometimes you forget how many people watch the show, I am mind-blown.”
