While Formula 1 star Charles Leclerc continues to cement his name on the track, his girlfriend, Alexandra Saint Mleux, is making waves in an entirely different field.

The social media star has been thriving in the fashion world, staying booked and busy with a string of high-profile events. Among her most recent appearances was with Jacquemus’ show.

The French designer delivered a spectacular event showcasing the brand’s Spring/Summer 2026 collection in Versailles.

As the runway displayed minimalist silhouettes with dramatic flair and couture-level detail, the Formula 1 WAG opted for a simple and effortlessly chic look.

Along with celebrities like Matthew McConaughey and his wife, Camila Alves, as well as fellow influencers and fashion key players, Saint Mleux stepped out in a daring outfit.

The TikTok star wore a white maxi dress with a deep V neckline and cut-out back detail, creating an elegant and effortlessly sophisticated style.

While her outfit reflected minimalism, she went for bold gold earrings and a black handbag to complement the look.

Her glamorous ensemble immediately caught the attention of fans and fashion watchers alike.

“The body is tea,” a commenter said in a post shared by celebrity and women's magazine account Gala.

“She’s totally a beauty,” another added.

TikTok users continued to hype her look and said, “Super gorgeous, she pulled that dress really well.”

The 22-year-old has been dating the F1 star since 2023 after they were spotted together at Wimbledon and Paris Fashion Week.

Leclerc eventually addressed the dating rumors and confirmed he was seeing someone. Although he did not mention the girl’s name during the interview, the public speculated that it was Saint Mleux.
