The Prince and Princess of Wales have always shared a close relationship with Prince William's cousin, Zara Tindall, and her husband, Mike.
So much so that Zara was chosen as one of Prince George's godparents at his christening in 2013.
It appears that Zara has an equally strong bond with her godson, George, ten, as the royals turned out for the Christmas Day church service in Sandringham.
The equestrian, 42, was spotted putting her arms around the young prince as they made their way back to Sandringham House after the service.
The sweet moment was captured by Callan Taverner, as the royals stopped to speak with the crowds gathered near St Mary Magdalene church.
Zara looked beautiful in a dark green coat by Laura Green with black suede boots and a gold bow-shaped headband by Juliette Botterill Millinery.
She and her rugby star husband Mike were joined by their daughters, Mia, nine, and Lena, five, as they walked alongside the Prince and Princess of Wales and their children, Prince George, Princess Charlotte, eight, and five-year-old Prince Louis.

"Our kids play with their kids in this competition we have," explained Mike.

Equestrian Zara, who won a silver medal at the 2012 London Olympics, added: "I think our families are fairly competitive."
