Princess Caroline of Monaco Spouse and First Husband

Princess Caroline’s marital history reflects three distinct chapters of her adult life, each bringing different circumstances and challenges. Her first marriage at the age of 21 to French banker Philippe Junot drew significant international attention, while her second marriage to Stefano Casiraghi ended tragically with his untimely death in a speedboat accident.

First Marriage to Philippe Junot

Her initial venture into matrimony occurred in 1978 when, at just 21 years old, she married Philippe Junot in a ceremony that attracted over 600 guests to Monaco. The guest list read like a who’s who of Hollywood and international society, featuring luminaries such as Gregory Peck and Frank Sinatra. The union proved short-lived, however, ending in divorce in 1980. The Catholic Church later annulled the marriage in 1992, formally declaring it had never been sacramentally valid.

Second Marriage to Stefano Casiraghi

The civil ceremony with Italian sportsman and heir Stefano Casiraghi took place on 29 December 1983. Stefano, born in 1960, represented a new chapter filled with promise until tragedy struck on 3 October 1990. He died at age 30 in a devastating speedboat accident, leaving Princess Caroline a widow at 33 with three young children. The loss profoundly shaped her subsequent approach to family and public life.

Current Marriage to Prince Ernst August of Hanover

Her third and current marriage brings her into connection with the House of Hanover, one of Europe’s oldest noble houses. Prince Ernst August of Hanover, head of the Hanoverian dynasty, married Caroline civilly on her 42nd birthday, 23 January 1999, following his divorce from Chantal Hochuli. The couple eventually separated around 2009, with Caroline returning to Monaco, though they remain legally married. She adopted the title Princess of Hanover, reflecting her new family’s noble designation.

Princess Caroline of Monaco Age

As of 2026, Princess Caroline is 69 years old, having been born on 23 January 1957 in the Prince’s Palace of Monaco. Her birth date places her just over a year ahead of her brother Prince Albert II, who was born on 14 March 1958, making her the eldest of the three Grimaldi children.

Throughout her life, Caroline has navigated the particular challenges of royal life while aging with dignity and purpose. Her early years were marked by intensive education, including studies in Monaco, Paris, and London, where she developed fluency in multiple languages. Grace Kelly herself described her daughters as “warm, bright, amusing, intelligent and capable,” noting their skills across academics, sports including skiing and swimming, cooking, sewing, piano, and horse riding.

Now at 69, Princess Caroline has witnessed significant changes within Monaco’s royal structure. She served as heir presumptive to the throne from birth until Albert’s birth, then again from 2005 to 2014. Today she ranks third in the line of succession, behind Prince Albert’s twins. Her role has evolved from the pressures of potential succession to one focused on family stewardship, philanthropy, and cultural engagement.

Princess Caroline of Monaco and Grace Kelly

The relationship between Princess Caroline and her mother, Grace Kelly, defined much of her childhood and early development. Born to an American film star and a European monarch, Caroline embodied the unique convergence of Hollywood royalty and traditional European nobility from her very first days.

Grace Kelly’s transition from Oscar-winning actress to Princess of Monaco required significant adaptation, and her approach to motherhood within this extraordinary context shaped both Caroline and her younger sister Princess Stéphanie. The family maintained residences in Monaco while also spending considerable time in the United States, particularly at their estate in Philadelphia, ensuring the children maintained connections to both worlds.

Caroline’s heritage reflects this transatlantic lineage. Through her father’s side, she descends from French nobility connected to the Dukes of Polignac, while her mother’s ancestry brings Irish and German elements to the family’s genetic composition. This aristocratic lineage has been maintained and passed down through subsequent generations.

Grace Kelly’s tragically early death in September 1982, following a car accident, occurred when Caroline was 25 years old. The loss profoundly affected the entire family, particularly impacting Caroline’s understanding of her own future roles and responsibilities within the Grimaldi dynasty.

The year 2026 marks a significant milestone for Princess Caroline, who celebrated her 69th birthday on 23 January. This occasion provided an opportunity to reflect on her enduring presence within Monaco’s royal family and her contributions across philanthropy, culture, and the arts.

Recent family developments have brought additional joy, most notably the birth of her newest granddaughter Bianca Caroline Marta Casiraghi on 4 October 2025. Born in Monaco to Pierre Casiraghi and his wife Beatrice Borromeo, Bianca represents the latest continuation of the Grimaldi line, carrying Caroline’s middle name as part of her own.

Her children continue to establish themselves across various fields. Charlotte Casiraghi has become particularly prominent in fashion and business circles, while Andrea and Pierre manage their respective family interests. Princess Alexandra of Hanover, her youngest, represents the Hanoverian branch of her extended family.

Princess Caroline’s public engagements continue to focus on cultural and educational initiatives, building on her lifelong interests. Her biography from the official Monaco Palace website emphasizes her dedication to these sectors alongside her family responsibilities.
