Princess Beatrice and Edoardo Mapelli Mozzi celebrated their daughter Sienna's second birthday on Monday, and the property developer shared a rare photograph to mark the occasion.
Edoardo posted the sweet snap on Instagram, writing: "Happy Birthday Baby Girl. You bring us so much love and joy every day."
The image showed little Sienna, with her back to the camera, wearing a long-sleeved pink and red floral dress with a wide-brimmed straw party hat.
The picture appears to have been taken outside, with a walled garden seen in the background.
Beatrice and Edoardo have not shared any official images of Sienna since her birth in 2021, preferring to keep their daughter off their social media accounts.
Earlier this year, Beatrice's sister, Princess Eugenie, shared a sweet photo of her eldest son August with Sienna as the cousins enjoyed a play date at London Zoo.
Sienna has also not joined her parents for any formal public events. The little girl is currently tenth in line to the British throne, but is not likely to become a full-time working royal in the future.

Beatrice and Edoardo tied the knot in Windsor in an intimate ceremony in July 2020, when there were restrictions around weddings due to the COVID-19 pandemic at the time.
