Rose Hanbury, the Marchioness of Cholmondeley, was among the guests to join the royals on the final day of the Badminton Horse Trials in Gloucestershire on Sunday.
The British peeress, 40, wearing a cyan blue trouser suit and pale blue shirt, was pictured curtseying to Queen Camilla as the pair chatted alongside beauty entrepreneur, Charlotte Tilbury.
Rose, who is married to David Cholmondeley, 7th Marquess of Cholmondeley, was seen watching the action from the stands at the equestrian event along with Zara Tindall's brother, Peter Phillips and his daughter, Savannah and Isla.
The Cholmondeleys are friends of the Prince and Princess of Wales and reside at Houghton Hall in Norfolk, close to Prince William and Kate's country home, Anmer Hall.
