Princesses Eugenie and Beatrice have long held the status of having the sweetest royal sisterhood. The York daughters—their parents are King Charles’s brother Prince Andrew and Andrew’s ex-wife, Sarah Ferguson, Duchess of York—have always held an obviously close bond, typically appearing side by side at royal events before their marriages and even now are frequently seen together. Over the weekend, they cemented their status once again, as Eugenie shared a charming post celebrating her older sister Beatrice’s birthday, including a special message and a series of photos of the sisterly duo.
“Happy happy birthday to my dearest Beabea,” Eugenie wrote on her Instagram. “My big sissy, the best in the entire world.” Along with the message, Eugenie included photos of Beatrice solo, as well as the two of them together, including a playful shot of them grabbing a bite to eat together, as well as a cute moment out and about with their mother.
While both Beatrice and Eugenie are nieces of the king and part of the line of succession, neither of them hold the position of working royals. Instead, both women carry out their own personal and professional lives, occasionally stepping in to help with family functions and maintaining their own patronages and charities. Last year, in particular, the duo were active on the royal roster when King Charles and Kate Middleton were both in the midst of their separate battles with cancer.
Princess Eugenie, who works full-time as a director at the art gallery Hauser & Wirth, is also a mom of two boys, August and Ernest, with her husband Jack Brooksbank. “I think I’ve got a good balance. I’ve got an amazing husband and team and projects I’m passionate about. I’d feel uneasy if I wasn’t doing my charity work, looking after my family and doing my job. I love what I do,” Eugenie shared in a rare interview earlier this year.
Beatrice, who became a Counsellor of State in 2022, has her own brood, having welcomed her second daughter, Athena, in January. She also shares her daughter Sienna with her husband Edoardo Mapelli Mozzi, as well as Edoardo’s son from a previous relationship, Christopher “Wolfie” Woolf.
