What is Princess Stéphanie of Monaco's net worth?
Princess Stéphanie of Monaco, the youngest daughter of Prince Rainier III and Hollywood icon Grace Kelly, has a net worth of $100 million. Princess Stéphanie has led a life that defies royal convention. From fashion and music to humanitarian work and the circus arts, Stéphanie has consistently defied tradition and forged her own unique identity. Known for her rebellious streak and fiercely independent spirit, she remains a central and complex figure in the modern history of Monaco.
Early Life and Education
Stéphanie Marie Elisabeth Grimaldi was born on February 1, 1965, in Monte Carlo, Monaco. She is the third child of Prince Rainier III, who ruled Monaco for over five decades, and Grace Kelly, the American actress who gave up a successful Hollywood career to become Princess of Monaco. Stéphanie grew up in the Palais Princier alongside her older siblings: Princess Caroline, born in 1957, and Prince Albert, born in 1958 and the current reigning monarch of Monaco.
As a child, Stéphanie enjoyed a privileged yet closely scrutinized upbringing. She attended the Dames de Saint-Maur in Monaco before continuing her studies at the Dupanloup school in Paris. A bright and artistic student, she studied classical dance and piano and developed a passion for fashion, athletics, and travel. She became fluent in French, English, and Italian, and earned her French Baccalaureate in 1982.
Tragedy and Resilience
That same year, Stéphanie's life was forever altered. On September 13, 1982, while returning from the family's country estate in Roc Agel, she was a passenger in the car driven by her mother, Princess Grace, when it veered off a cliffside road. Grace suffered a stroke behind the wheel and died the following day from her injuries. Stéphanie, just 17 at the time, was hospitalized with serious injuries and missed her mother's funeral. Rumors and speculation surrounding the crash followed her for years, despite official statements that confirmed Grace was driving.
The trauma of the accident had a profound effect on Stéphanie, who later described herself as having to "rebuild" her life. She emerged from the tragedy with a defiant energy and began to pursue interests outside traditional royal protocol.
Career in Fashion and Music
After recovering from the accident, Stéphanie pursued a career in fashion. She interned at Christian Dior under designer Marc Bohan, gaining hands-on experience in haute couture. In 1986, she launched her own swimwear line, Pool Position, which she designed and promoted in Monaco.
That same year, she released the French-language pop single "Ouragan," which became a massive commercial hit across Europe, selling over two million copies. Her debut album, Besoin, followed soon after and included a string of popular tracks. In 1991, she released a second album, though it received a more muted response. Stéphanie also collaborated with Michael Jackson on the hit song "In the Closet," providing the mysterious female vocals credited only as "Mystery Girl."
Though her music career was relatively brief, it solidified her image as a princess willing to take creative risks and engage with global pop culture on her own terms.

Personal Life and Family
Princess Stéphanie's personal life has long captivated tabloids and royal watchers. She has three children: Louis Ducruet (born 1992) and Pauline Ducruet (born 1994) with her former bodyguard Daniel Ducruet, whom she married in 1995 and divorced a year later following a public scandal. Her third child, Camille Gottlieb, was born in 1998. Camille's father, former palace guard Jean-Raymond Gottlieb, was never formally acknowledged on the birth certificate due to Monaco's laws regarding succession.
In 2003, Stéphanie married Portuguese circus acrobat Adans Lopez Peres, a member of a respected circus family. The marriage ended in divorce in 2004. Throughout her life, she has raised her children largely outside the royal spotlight, prioritizing their privacy and education.
An avid supporter of the arts and animals, Stéphanie embraced the world of the circus in the 2000s. Her passion for performance and respect for the circus tradition led her to take over as President of the International Circus Festival of Monte-Carlo after her father's death in 2005. She has also advocated for the preservation of traditional circus arts, even as criticism of animal performance grew in Europe.
In 2004, she founded Fight AIDS Monaco, an organization aimed at combating HIV/AIDS and supporting those affected by the disease through education, advocacy, and direct assistance. Stéphanie has been hands-on in the organization's work, often visiting patients, participating in fundraisers, and representing the cause globally as a UNAIDS ambassador.
Evolving Image and Public Role
Although once branded the "wild child" of Monaco's royal family, Stéphanie's public image has matured over time. Her commitment to causes like HIV awareness and her quiet dedication to her children and charitable work have earned her respect in Monaco and abroad. Unlike her older sister Caroline, who often represents the principality at official events, Stéphanie tends to avoid the spotlight unless it involves causes she personally champions.
