Kate and William share adorable rare family video for anniversary

Prince William and Kate Middleton have shared a beautiful family video, showing what life is like for them and their three children as they celebrate their 10th wedding anniversary.

The candid video was filmed in autumn last year and shows the family playing in sand dunes and roasting marshmallows on a fire.

In the video, Prince George was likely seven, Princess Charlotte was about five years old and Louis was around two.

In one part of the video, Kate and William chase their laughing kids around the garden, while in another on a chillier looking day trip, they snuggle together at the beach and watch the waves.

Body language expert Judi James told The Sun, it was evident in the video that the couple is prepping "reserved" Prince George for his future as King.

"All three children seem to be developing different personalities and the way that George looks rather grown-up, thoughtful and slightly reserved here suggests the coaching from William is paying off for the future heir to the throne," she said.

"William and Kate must be aware of their role in their children's destiny.

"They know that the pressure of royal life will start to be apparent for them before long but it’s wonderful seeing all three of them being so noisy, boisterous and spontaneously happy in the meantime, all with the blessing and encouragement of their playful and very proud-looking parents."

Last year, it was reported that William and Kate explained to George that he'll be King one day by telling him it's "like a storybook", according to a source at Us Weekly.

Some also believe Kate was paying tribute to her late mother-in-law, Princess Diana, with her pie crust collar, which was a favourite of Diana's.

"Thank you to everyone for the kind messages on our wedding anniversary," they wrote on Instagram. "We are enormously grateful for the 10 years of support we have received in our lives as a family. W & C."

Fans of the couple shared their well wishes with some even feeling emotional after watching the video.

"This is so beautiful. I'm crying," wrote one fan.

"Oh my goodness this is the most precious little treat! Happy anniversary!" another added.

"Why did this make me incredibly emotional. Happy Anniversary to a beautiful couple! And what an amazing family and life you have created together," someone else shared.

It comes after the pair shared two smiling new portraits to celebrate their anniversary.

The couple appeared very much in love in the photos where they wore matching blue outfits and beamed at the camera.

Kate and Will married on 29 April 2011 in Westminster Abbey, followed by a reception at Buckingham Palace.
