But perhaps her best accessory was her dashing boyfriend, Ben Sylvester Strautmann, who joined the Princess over the weekend. The handsome heir to a prominent German business dynasty, Strautmann grew up in Monaco and made his debut beside Alexandra in 2017. Since then, the couple have been inseparable, appearing at everything from museum openings to Grand Prixs. The loved-up pair are now regular fixtures on the social scene – and wedding bells might one day chime.
Born in Austria and raised in Monaco, Alexandra once competed internationally as a junior figure skater, even representing her principality at the European Youth Olympics. She attended school at the prestigious L’Institution François d’Assise–Nicolas Barré, but these days, she’s best known for her front-row fashion credentials. Whether at Dior, Stella McCartney or her beloved Chanel, she’s become a regular on the fashion circuit.
While the princess is the only child from her parents’ marriage, she has a gaggle of glamorous half-siblings with whom she has a close relationship: her father’s sons, Hereditary Prince Ernst August and Prince Christian of Hanover, and her mother’s children from her second marriage: Andrea, Pierre and Charlotte Casiraghi. Her sister-in-law is Beatrice Casiraghi, who in the August 2023 issue of Tatler, discusses her personal connection to the shocking scoop that rocked European high society.
