Kate Middleton and Zara Tindall share a special friendship.

The members of the royal family are growing especially with the arrival of the royal babies. But the grown-ups remain close to each other like Zara and Middleton.

Express shared snaps of the Duchess of Cambridge with Zara and there sweet photos together speak volume about their friendship.

Middleton and Zara regularly appear together at certain events. In June, they were photographed greeting each other with a hug and kiss at the Royal Ascot. They enjoyed a conversation as they waited for the race to start.

Middleton and Zara became friends because Prince William is very close to his cousin. In 2007, when the Duke and Duchess of Cambridge were tentatively getting back together after they split, Middleton was seen attending Concert for Diana where she was seated behind Zara. They were photographed smiling while talking, and it convinced many that they have a great friendship.

Prince William and Middleton’s children are also close to Zara and Mike Tindall. A few months ago, the Cambridges and the Tindalls stepped out together. The two families seemed to have fun, but what didn’t escape the eagle-eyed fans was Prince George’s sweet moments with aunt Zara.

Prince George and Zara were photographed giving each other a high five. They were also seen hugging one another.

Earlier that day, Prince George perched on Mike’s shoulder. Meanwhile, Zara’s daughter was on Prince William’s shoulder.

“Zara’s family and Cambridges family. A big friendship,” one netizen commented in the photos.

Mike revealed that his kids with Zara are close to Prince William and Middleton’s children because they are close in age, so they can easily relate to each other and enjoy their fun time together. Middleton and Zara’s youngest kids Prince Louis and Lena are about the same age. Meanwhile, Mia is between Princess Charlotte and Prince George’s age. Mike hopes that they would keep their friendship as they grow older.
