Pierre Casiraghi, the son of Princess Caroline of Monaco and grandson of American actress turned royalty Grace Kelly, joined the French fashion house as a representative on October 13, according to WWD. Pierre's wife, Italian model Beatrice Borromeo, was previously named a Dior ambassador in February — which is not a surprise, given that she edged out the likes of Kate Middleton and Meghan Markle to be named the most stylist European royal by Tatler earlier this year. In June, the couple attended a Dior show in Athens together. Pierre Casiraghi and Beatrice Borromeo.

The Monegasque businessman embodies the new facet of tailoring constantly reinvented by Kim Jones [creative of Dior's men's line], a timeless modernity," Dior said in a press release about the 34-year-old businessman, who is eighth in the line of succession to the Monegasque throne. Brett Lloyd Monaco's royal family are familiar with the fashion scene, particularly Dior. Pierre's grandmother Princess Grace commonly wore the brand, including to her 1956 engagement party in New York City. His aunt Princess Stephanie worked at Dior as an intern under designer Marc Bohan in 1980s. Pierre's sister Charlotte Casiraghi has been a brand ambassador for Chanel since last year, while his cousin Pauline Ducruet has her own gender neutral fashion line, Alter.
