Princesses Beatrice and Eugenie celebrated a royal relative last weekend.

The sisters attended the third (yes, third) wedding ceremony of Prince Philippos of Greece and Nina Flohr in Athens. Beatrice was photographed at the event with her husband, Edoardo Mapelli Mozzi—her first appearance since welcoming her first child, Sienna Elizabeth Mapelli Mozzi, last month.

Prince Philippos, 35, is Princess Diana‘s godson and a distant relative of the sisters through the late Prince Philip. His father, King Constantine III—who is also Prince William‘s godfather—and his mother, Queen Anne-Marie, were also in attendance at the ceremony.

The prince first married VistaJet creative director Nina Flohr at the Swiss ski resort St. Moritz in December. Their fathers were the only attendees at the intimate ceremony, due to Switzerland’s strict COVID-19 restrictions, per People. They celebrated their union again at a springtime event in Cambridgeshire last May.

The bride, now Princess Nina of Greece and Denmark, wore a white silk taffeta gown with a V-neckline, an empire waist decorated with a front bow, and a full pleated skirt with a sweeping train. She also wore the Antique Corsage pearl-and-diamond tiara, which was gifted to Queen Anne-Marie on her 18th birthday in 1964, per The Court Jeweller.
