[1] Her mother, who described Stephanie as a "warm, bright, amusing, intelligent and capable girl" and a "good athlete", lovingly called her "wild child" (French: enfant terrible).

Stéphanie herself refused to speak publicly about her mother's death until 1989, when she gave an interview to the author Jeffrey Robinson, insisting that the story was untrue.

"[4][5] Princess Stéphanie was educated at the Dames de Saint-Maur in Monaco, and then at the école and collège Dupanloup in Boulogne-Billancourt, France.

[7] In 1983, after her physical recovery from the accident that killed her mother, Stéphanie started an apprentice programme at Christian Dior under the direction of head designer Marc Bohan.

[8] The following year, she debuted as a model on the biannual haute couture special published by Spanish magazine ¡Hola!, a venture that she repeated in 1990.

In 1986, Stéphanie launched a swimwear line Pool Position with Alix de la Comble, whom she had met during her internship at Dior.

The fashion show to present the line, held at the Sporting Club in Monaco and attended by her father, Prince Rainier, and siblings, Caroline and Albert, was a major event covered by the worldwide media.

The album Stéphanie, released in 1991, met with disappointing sales and negative reviews,[15] despite the promotional tour that included a performance on The Oprah Winfrey Show.

She made a brief return to singing in 2006, when she recorded "L'Or de nos vies", a charity single, along with her foundation Fight AIDS.

She has also been the patron of the International Circus Festival of Monte-Carlo, which she regularly attends,[18] and the World Association of Children's Friends (AMADE), which was founded in 1963 by her mother.

[22][23][24] Stéphanie dated Paul Belmondo,[25] Anthony Delon,[26] Rob Lowe, Mario Oliver Jutard, and the late Jean-Yves Le Fur (1964-2024) before she began a relationship with her bodyguard Daniel Ducruet in 1992.

The children were included in the line of succession to the Monegasque throne when Stéphanie married Ducruet on 1 July 1995 at Monaco town hall.
