Kate helps the Queen and Princes William and Harry honour athletes at Buckingham Palace

The Queen received some help from her sporty grandsons Prince William and Prince Harry and granddaughter-in-law Kate in welcoming Olympic and Paralympic athletes to Buckingham Palace for a celebratory reception on Tuesday night (Oct 18).

They royals mingled with many of the British stars of the Rio 2016 Olympic games, circulating the palace's State Rooms, discussing victories and congratulating the athletes on their successes.

Kate stunned in Alexander McQueen, wearing a floor-length white gown emblazoned with patriotic red poppies.

Princess Anne, who is president of the British Olympic Association and a member of the International Olympic Committee, also joined the celebrations, as did Prince Andrew.

The Queen looked splendid in green as she greeted British Prime Minister Theresa May.

Her Majesty, who previously praised the Team GB squad for the "magnificent" performance in Rio, hosted a similar celebration after London 2012.

Although Kate, William and Harry were not able to attend the events in Rio this summer, they did record a video wishing the athletes the best of luck at the games.

"Our athletes are an inspiration to us all and we need the whole country to get behind them and cheer them on as they take to the world stage," said Harry.

William added: "We have some of the most passionate supporters in the world and we can't wait to cheer on our athletes together this time in Rio."
