King Charles and Queen Camilla are being treated to a star-studded evening to celebrate their Coronation, with a concert taking place at Windsor Castle.
Take That, Katy Perry and Lionel Richie are all on the line-up, but it's a 13-year-old girl who has captured their attention.
Blind pianist Lucy Illingworth won Channel 4's show, The Piano in March and was given a coveted spot to perform on stage at the Coronation Concert.
Lucy performed a rendition of Bach's Prelude in C Major for the Royal Family and her impressive talent clearly made many people emotional - including Camilla, who appeared close to tears while watching.
The King and Queen watched closely and gave the 13-year-old a round of applause when she finished her note-perfect performance.
And they aren't the only ones who were moved by Lucy's skills, as those watching the concert at home flocked to Twitter to share their thoughts, agreeing she was a 'star' and had 'stolen the show'.
One said: "Can't get over Lucy's talent. Favourite part of the Coronation Concert so far."
Another wrote: "I found this piece very moving. Bravo, Lucy."
Someone else posted: "Stand out star so far is Lucy, on the Steinway piano!"
"Oh Lucy, you are amazing," proclaimed a fourth.
While a different user added: "This young lady has had me blubbing in 30 seconds. Absolutely amazing."
Lucy, who is blind and neurodiverse, melted the hearts of the nation on Channel 4's The Piano when she performed Chopin's Nocturne in B flat minor at Leeds Train Station.
She then continued on to victory at the show's Grand Final in London.
The teenager is a part of the Amber Trust, a charity that Queen Camilla is patron of.
The trust, which provides musical opportunities for blind and partially sighted children, previously shared their pride at her being chosen to perform at the concert.
They posted on their website: "We are thrilled that Lucy has the opportunity of participating in such a historic moment, celebrating the Coronation of His Majesty The King and Her Majesty The Queen Consort."
