Princess Eugenie has marked her sister Princess Beatrice’s 36th birthday by sharing some very sweet photos on Instagram.

The first two show the sisters on holiday, while the last is Beatrice with her nephew. The adorable picture appears to be taken at Easter, as the youngster is sat surrounded by spring daffodils and Beatrice is donning some bunny ears. It’s not clear whether the child is August, Eugenie’s firstborn aged three, or Ernest, aged 14 months.

Accompanying the images, Eugenie wrote: “Happy birthday dearest Beabea!! What an inspiration you are. You’ve paved the way for your little sissy. Love you xx.”

Royal fans were delighted by the new pics, with one fan writing: “That last photo – we love an awesome Auntie!”

Another said: “Happy birthday Beatrice!!!. Love the photos! Thanks for sharing!”

Another fan commented: “Happy birthday Bea [heart-eyed emoji] [red-heart emoji].”

A fourth simply wrote: “Best wishes !!!!!!!”

The eldest daughter of Prince Andrew and Sarah Ferguson was born on at 8.18pm on August 8, 1988 at the Portland Hospital in London – with many fans noticing a weird coincidence in her birth date and time.

Posting on X, formerly known as Twitter, one fan wrote: “I’m not superstitious or anything but wow…how many 8’s are linked to her birth,” followed by a mind-blown emoji.

Others were quick to comment on the strange coincidence too. One responded: “Is it just me that remembers the reporting that she was induced to be born on 8.8.88 as 8 is lucky in China and they thought it would be extremely good luck? Maybe it’s one of those false memories.”

Princess Beatrice married to Edoardo Mapelli-Mozzi in 2020, with the late Queen and Prince Philip among the guests.

The couple now share a daughter named Sienna, who will celebrate their third birthday next month. Beatrice is also a doting stepmother to Edoardo’s eight-year-old son Wolfie.
