Among those who has long been by the couple’s side is Princess Nina and her husband, Prince Philippos of Greece and Denmark, of the defunct Greek royal family. Philippos is the son of the late Constantine II, the last King of Greece, and the younger brother of Crown Prince Pavlos of Greece.

Nina (née Flohr) is the only child of VistaJet businessman Thomas Flohr and his wife Katharina (the couple are now divorced). Flohr previously worked for her father’s business as creative director, but is now an entrepreneur in her own right. She has been friends with Beatrice for more than a decade, having met the Princess long before her future husband. The pair move in social circles that include Alice Naylor-Leyland and Olivia Buckingham.

In 2018, Nina began dating Prince Philippos, of the storied Greek dynasty. The couple attended a number of high profile weddings together – including those of Princess Eugenie and Jack Brooksbank, and Lord Edward Spencer-Churchill and Kimberly Hammerstroem – before becoming engaged in 2020.

The couple were married in December 2020 in a civil ceremony in the bride’s hometown of St Moritz. Due to the pandemic, just four people were in attendance – the bride, the groom, and both of their fathers, King Constantine of Greece and Denmark and Thomas Flohr. However, the following year, the couple celebrated their nuptials with friends in the UK. Alice and Tom Naylor-Leyland opened the doors of their Stibbington House to throw the newlyweds a chic bash attended by Violet Henderson and Caroline Rupert.
