Rose Hanbury, the Marchioness of Cholmondeley, attended the final day of the Badminton Horse Trials, along with Queen Camilla and the Tindalls.
Rose, 40, wore a blue suit and shirt as she joined Camilla to watch the action on the final day of the equestrian event in South Gloucestershire.
Meanwhile, Princess Anne’s daughter Zara Tindall was spotted trotting to an inspection with her horse Class Affair earlier today.
Zara, an Olympic silver medalist, looked effortlessly elegant in a pinstripe blazer and white trousers paired with a matching top as she accompanied her horse.
The king’s niece had her blonde locks tied back and accessorized with stylish sunglasses, while Camilla completed her ensemble with brown heels.
Rose – who is married to David Cholmondeley, the 7th Marquess of Cholmondeley – was seen smiling and chatting in the crowd as she joined the senior royals for the event.

Zara’s son Lucas, three, wore a Spiderman hat with blue shorts and a shirt in a matching shade.
His father, Mike, seemed as prepared for the warm weather as his children, wearing khaki shorts, a black shirt with the sleeves rolled up, a cap and sunglasses.
The family seemed to have loads of fun during the action-packed day out – with the children seen wearing big smiles in the Badminton House grounds.
Queen Camilla looked chic in a blue summer dress on day four of the Badminton Horse Trials on Sunday.
The Queen attended the final day of the Badminton Horse Trials and presented trophies to the prize winners to celebrate the 75th anniversary of the event.
Camilla, as patron of British Equestrian, watched the final show jumping stages of the competition in Gloucestershire and then presented trophies in the arena.
She met guests involved in the trials, including representatives from the British Equestrian Federation, past winners of the competition, as well as volunteers and officials involved in this year’s event.
