Queen Camilla looked distressed as her hopes were dashed during Royal Ascot.
Charles and Camilla’s thoroughbred Gilded Water ran in the King George V Stakes, the same race that gave them their victory last year.
Camilla was entirely absorbed in the race as she watched her horse run through a pair of binoculars.
However, the couple were shocked when the horse did not make it over the finish line first, with Going the Distance crossing the line.

Despite her dour expression, Camilla looked beautiful as she wore a stunning white and matching race day sun hat alongside an emerald green brooch.
The King donned a grey morning suit with a vibrant blue waistcoat and paired the outfit with a black top hat.

The King looked in good spirits today as he led the carriage procession with his wife Queen Camilla and the Duke and Duchess of Devonshire.
Princess Margaret's children, the Earl of Snowden and Lady Sarah Chatto also took part in the procession as well as Mike and Zara Tindall.
The King has attended three out of the four days of Royal Ascot so far.
The King, 75, reportedly told courtiers he wants to honour the memory of his late mother by attending this summer's Royal Ascot, despite undergoing cancer treatment.

King Charles plans to spend "at least" one day at the racing festival and will host a lunch for a select "bubble" of friends and family, according to reports.
Earlier in the year a source told The Mail: "Ascot is the perfect event for his current 'bubble'-style distancing preferences – there will be lots of fresh air and plenty of chances to be seen by royal fans who will be desperate to get a glimpse."
Last year’s Royal Ascot saw a huge win for The King, with his horse, Desert Hero, overcoming odds of 18 to 1 to land first place.
Francis Brooke, Charles’ representative at Ascot, said the win was the "highlight of the week," with Hero winning in "thrilling style".

In a statement before Royal Ascot this year Charles and Camilla said: "It gave us immense pleasure and joy to witness Desert Hero’s victory in the King George V Stakes last year, particularly as he was bred by Her late Majesty.
"We wish all the participants this week the very best of luck in seeking that unique thrill of a Royal Ascot winner."
"We also hope that those here at the racecourse and watching from home will enjoy five days of the finest racing that this sport has to offer."
