While dancing at
Le Palace in 1979, Khelfa was discovered by designer Jean Paul Gaultier. Gaultier would cast her in his 1980 fashion show, launching her modeling career. In the following years, she would become the muse to many important figures in the fashion world, including
Jean-Paul Goude,
Azzedine Alaïa, and
Thierry Mugler. Khelfa stepped down as brand ambassador in 2017, stating that she needed time to focus on her own projects, particularly filmmaking. Despite this, Khelfa has continued to work with the brand, notably appearing on the Schiaparelli spring/summer 2020 Haute Couture runway in 2019. Most recently (as of April 2026), she worked with them in December 2024 on a photoshoot for
7 Hollywood Magazine. In 2024, Khelfa wrote her first book, a memoir titled
Une enfance française. ==Personal life==
