Saint Mleux was born in Italy in 2002, from an Argentinean father and a Mexican mother, as reported by Vanity Fair. Saint Mleux is as worldly as her heritage, with her speaking French, Italian, and English. She also studied art history at the L'Ecole de Louvre, with a specialization in 20th-century art. Over the years, she's worked in the field as an art assistant at the Hôtel Des Ventes De Monte-Carlo auction house and on Monaco Art Week. 

Aside from her work as an influencer, Saint Mleux currently runs an Instagram art account. This love of art and culture is likely something that brought her and Leclerc together, with him being a known lover of the piano, even composing his own songs.

A year ago, Saint Mleux had a private Instagram account with only a thousand followers. Now, she's a significant influencer, having over 3 million followers and partnerships with different brands, including Hailey Bieber's Rhode.

Following her rise in popularity, Saint Mleux used the attention to launch a charitable organization called the Corazones Unidos Fund, established with the goal of providing Mexican children with access to education, music, and the arts. 

"Corazones Unidos was born from the belief that kindness, even in it’s smallest form, can change lives," she wrote in an Instagram post. "Our goal is to help children, especially girls, continue their education, explore their creativity, and feel empowered to dream bigger, while also supporting women in the arts, helping their voices and talents reach the world."

Charles Leclerc and Alexandra Saint Mleux have only started sharing more details about their relationship in recent months, after the couple shared news of their engagement.
