Princess Eugenie has today shared the first photo of her sister Princess Beatrice's one-year-old daughter, Sienna Mapelli Mozzi.
She published a picture showing her son August Brooksbank and her niece Sienna as they look as they admire penguins during a day out at the London zoo.
Posting the photo to celebrate Earth Day, Eugenie said the two cousins love going to the zoo and looking at animals.
The image features Sienna and August facing the penguin pool at the zoo, and shows Beatrice's daughter, who has not been pictured before, with blonde hair.
The girl, who was born in September 2021 and is turning two in a few months, is wearing a fleece jacket with a hood, light blue jeans and black boots.
Her cousin August, two, is also wearing a jacket, jeans and boots as he looks at penguins in their enclosure.
Posting a series of photos this morning, Princess Eugenie said: "August and his cousin Sienna love going to the London Zoo. It's part of the Zoological Society of London, a global wildlife conservation charity that helps to restore habitats and protect wildlife. Every time you visit you are supporting their work."
She also published two images of little August at BBC Earth experience in London, which is located in a sustainable building dedicated to nature and conservation.
Next, Eugenie posted two photos of her at work with a charity that aims to protect the ocean and is working to bring native oysters back to their habitat.
The final photo of her series is a snap of Eugenie's husband, Jack Brooksbank, walking with their son August in woodland, that she captioned: "Because I love them and they love nature."
Eugenie is passionate about the environment and previously said she is teaching her son to become an activist too.
Speaking at the World Economic Forum in Davos, Switzerland, earlier this year she explained: "At home we have no plastic, we try to as much as possible have no plastic and I'm trying to teach him that. But it's a battle."
Eugenie, who is now expecting her second child, added: "My son's going to be an activist from two years old, which is in a couple of days. So, he ... everything is for them ...
"I talked to Peter Thomson, the UN Special Envoy for Oceans and all he says to me is that I do this for my grandchildren. And that's the same.
"Every decision we now make has to be for whether August, what he's going to be able to look at and do and how he's going to live his life."
She also added that, together with her husband, she is trying to attempt the use of plastic at home to ensure her son is aware of climate change issues.
She said: "At home we have no plastic, we try to as much as possible have no plastic and I'm trying to teach him that. But it's a battle."
Eugenie's second pregnancy was confirmed by Buckingham Palace in January with a statement that said: "Princess Eugenie and Mr Jack Brooksbank are pleased to announce they are expecting their second child this summer.
"The family are delighted and August is very much looking forward to being a big brother."
Also announcing the news on her personal Instagram account, Eugenie shared a photo of her young son August kissing her bump.
In the photograph, taken by Mr Brooksbank, Eugenie, dressed in a woolly hat, beams as August, in a burgundy winter hat, matching trousers and wellies, embraces her and kisses her bump, as they stand next to a fence in a leaf-strewn field.
Eugenie wrote: "We're so excited to share that there will be a new addition to our family this summer."
