You’ve probably seen the headlines. Princess Beatrice is often the one wearing the bold fascinators at royal weddings or looking effortlessly chic at a London gallery opening. But lately, things have changed. Since the birth of Princess Beatrice and her daughter, Sienna Elizabeth Mapelli Mozzi, the royal has transitioned into a world of "glittery mackintoshes" and "unicorn cakes" that feels surprisingly relatable for a woman who technically lives in a palace.
Motherhood has clearly suited her. Honestly, it’s a bit of a departure from the strict, stiff-upper-lip upbringing we usually associate with the House of Windsor.
Why the World is Obsessed with Princess Beatrice and Her Daughter
Sienna was born on September 18, 2021, at the Chelsea and Westminster Hospital. From the jump, Beatrice and her husband, Edoardo Mapelli Mozzi, made it clear they weren’t going to follow the "baby on the steps" tradition. No photo calls. No public outings for months. They wanted privacy.
When they finally shared the name, it was a total curveball. "Sienna" wasn't even on the bookies' radar.
The name is actually a sweet nod to Beatrice’s Italian husband and her mother, Sarah Ferguson. The "S" is for Sarah, and the "Sienna" refers to the reddish-brown earth tones of Tuscany—a direct tribute to the famous red hair Beatrice and Fergie share. Sienna apparently has it too.
The Tiny New Addition
If you haven't been keeping up with the latest royal movements in 2026, the family just got bigger. Beatrice and Edoardo welcomed their second daughter, Athena Elizabeth Rose, in January 2025.

Athena arrived a bit early, weighing in at just 4 pounds and 5 ounces. It was a scary time, and Beatrice has been quite vocal lately about the "ordeal" of a premature birth and how lonely it felt. Thankfully, little Athena is healthy now. Sienna has officially stepped into her "big sister" era at four years old.
The Stealthy Royal Titles You Didn't Know About
Here is where it gets kinda complicated. Is Sienna a Princess? Technically, no—not in the British sense.
Under the 1917 Letters Patent, only the children and grandchildren of the Sovereign are automatically Princes or Princesses. Since Sienna is a great-grandchild of the late Queen Elizabeth II and a niece to King Charles III, she doesn't get the "HRH" title. But, because her dad, Edo, is an Italian Count, she actually has an international title.
- Sienna is a Nobile Donna (Noble Woman).
- She will eventually inherit the title of Contessa (Countess).
- She sits at 10th in the line of succession to the British throne.
- Her younger sister, Athena, is 11th.
It’s a weird mix of British commoner and Italian aristocracy. Basically, she’s more "titled" through her father’s lineage than her mother’s, at least on paper.
Raising a "Mini-Me" in the Spotlight
Sarah Ferguson has joked on her podcast that babysitting Sienna is like being transported back to the 80s. She calls the toddler "Sisi" and says she’s a carbon copy of Beatrice.

"When I'm following her, she looks just like Beatrice. She does the same thing as Beatrice. Beatrice is a Leo and it’s taken me right the way back... literally mini-me." — Sarah, Duchess of York.
They do normal stuff. Well, "royal normal." For Sienna's third birthday, they didn't have a banquet at Windsor. They had a unicorn cake from Tesco. It’s those little details that make people love Beatrice right now. She’s navigating the weirdness of being a royal while trying to give her daughter a childhood that involves puddlesuits and muddy wellies.
Beatrice is also a stepmother to Edo’s son, Christopher Woolf (known as "Wolfie"). She has frequently called him the "best big brother" to Sienna. Seeing them all together in those rare, blurry Instagram shots—Sienna in a cloud-printed puddle suit, Wolfie leading the way—gives a glimpse into a very modern, blended royal family.
Protecting the Privacy
You won't find many photos of Sienna’s face. Beatrice and Edo are strict about this. Most of the photos shared by the family show the back of her head or her little feet.
This isn't just about being "private." It’s a tactical move. In a world where every royal movement is scrutinized, Beatrice is giving her daughter the gift of anonymity for as long as possible. When they went to see the penguins at the London Zoo with their cousin August (Princess Eugenie's son), they were just another family in the crowd. Sorta.

What You Should Know About the Future
As Sienna and Athena grow up, their roles will likely stay "private." They aren't "working royals" and probably never will be.
- Education: Expect Sienna to follow the path of her mother, likely attending a top-tier private school in London or the countryside near their Cotswolds home.
- Italian Roots: The family spends significant time at Villa Mapelli Mozzi in Italy. Sienna is being raised to be as much Mapelli Mozzi as she is Windsor.
- Public Appearances: We might see her on the Buckingham Palace balcony for Trooping the Colour eventually, but don't expect a full-time royal life.
The way Princess Beatrice and her daughter are being positioned is a blueprint for the "slimmed-down" monarchy. They have the lineage, the history, and the titles, but they also have the freedom to just be a family.
If you're following the royal family's evolution, keep an eye on how Beatrice handles these next few years. She's successfully managed to stay relevant and beloved without the constant drama associated with other branches of the family.
