Princess Kate celebrated Mother's Day on March 30 by uploading a new video reflecting on how important nature has been during her cancer treatment and recovery. In a message accompanying the video, the Princess of Wales wrote: "Over the past year, nature has been our sanctuary.

"This Mother’s Day, let us celebrate Mother Nature and recognise how our bond with the natural world can help not only nurture our inner selves, but remind us too of the role we play within the rich tapestry of life. C." Princess Kate was celebrating Mother's Day in the UK with her three children - Prince George, 11, Princess Charlotte, 9, and six-year-old Prince Louis. The video featured a number of different natural environments from across the UK, including woodlands, fields, beaches and the ocean.

Clips included the slow unfurling of a daisy, fog rolling down a hill and a ladybird moving along a blade of grass.

Fans also noted there was perhaps a "new addition" in a furry form to the Wales family, upon close inspection of the video.

The Prince and Princess of Wales both briefly appear in the video, which showcases several natural environments across the UK.

Princess Kate appeared briefly to touch the bark of a tree whereas Prince William, 42, can be seen walking barefoot through a field accompanied by the family dog, Orla, alongside a brown Cocker Spaniel. Eagle-eyed royal fans were quick to speculate on if the Wales family have a new dog.

On social media, one royal fan wrote: "Guys, Orla has a new brother or sister."

Another said: "Footage of you & your puppy dogs is super cute", whereas a third said: "Does anyone know Princess Catherine’s new dog’s name?"

One added: "Princess Catherine has a new puppy."

The Wales family adopted their black Cocker Spaniel Orla in 2020 from James Middleton, Kate's brother, when the dog was eight months old.

Since going public with her cancer diagnosis, Katehas sought comfort from the natural world. Last July the Princess of Wales, who is now in remission from cancer, spoke about the "power of nature" as she helped to launch the Natural History Museum's Urban Nature Project.

At the time, she wrote a message on Instagram which in part read: "I know the power of nature to support our development and wellbeing, both by bringing us joy and helping to keep us physically, mentally and spiritually healthy."

The natural world also featured in a moving video message shared in September to confirm that Kate had completed a course of preventative chemotherapy.
