Queen Camilla stepped out at Royal Ascot today alongside her "most trusted companion".
Camilla, 77, was joined by Lady Sarah Keswick, one of the Queen’s Companions, who is often described as her closest confidante.
Lady Sarah Keswick was married to the late Sir John "Chips" Keswick, the chairman of Arsenal and a banking tycoon.
Throughout the years, the daughter of the 16th Earl of Dalhousie has been instrumental in several significant turning points in Charles and Camilla's romance.

Shortly after Camilla's divorce from Andrew Parker Bowles, she made her first public appearance with King Charles in 1995 at Sarah's 50th birthday celebration, which was hosted at the Ritz.
The late Chips Keswick was also very close to Queen Camilla, as the two even shared ownership of And Reach For The Moon, a horse that Queen Elizabeth II had raised.
Queen Camilla wore a Fiona Clare white coat for today's outing as well as her iconic horseshoe brooch.
The horseshoe-shaped brooch consists of diamonds, rubies and sapphires and she wears it on special race days.

It has a secret message that pays tribute to one of King Edward VII's racehorses, Minoru.
This is because the letters set within the brooch spell out the name "Minoru".
Minoru comes from the Japanese word meaning "bountiful abundance".
Queen Camilla also opted for her fluffy hat from the brand Lock & Co.
