The Princess of Wales cheered on the Prince of Wales as he competed in a charity polo match in Windsor on Thursday and the royal was joined by a number of guests on the side lines, including a family member!
Kate, who looked beautiful in a blue Beulah London dress for the occasion, was seen chatting and laughing with William's cousin, Peter Phillips.
The dad-of-two, 45, wearing a black blazer, white shirt and grey trousers, was seen watching the action with the Princess. See William on the polo field in the clip below...
Peter, who is the son of Princess Anne and her former husband, Captain Mark Phillips, generally keeps a low-profile but is often seen at major royal events, such as King Charles and Queen Camilla's coronation in May.
HELLO! exclusively revealed last month that Peter has returned to work on the Formula 1 circuit. His career first started some 20 years ago, first at Jaguar Racing and then Williams F1 and he is now head of partner acquisition for the sports and entertainment rights agency CSM Sport & Entertainment.
Peter has also found love again with his girlfriend of nearly two years, Lindsay Steven.
The pair have joined the royal family for several high-profile events over the past year, including the late Queen Elizabeth II's Platinum Jubilee celebrations last June, as well as the Epsom Derby and most recently, Royal Ascot.
A friend of the King’s nephew previously told HELLO!: "He is in a great place at the moment and could not be happier in either his private or personal life. Peter and Lindsay just look so natural and great together and are incredibly happy. They are both very private people, but the pictures of them at the Coronation Concert and those smiles just say it all.

The friend added: "Lindsay really is a breath of fresh air and it’s clear to see both Lindsay and Peter are loving life. On top of that, he has returned to the exciting world of F1. It is a boy’s dream to be working in that environment.
"Peter has always been extremely close to Charles, both when he was the Prince of Wales and now the King. It means a lot to Peter that Lindsay was allowed to take her place in the royal box by his side for a very important part of the coronation weekend."
