Leclerc shared this personal news on Instagram. It highlights how a driver's partner provides crucial support. For Leclerc, this engagement is a stabilizing force as he deals with the intense pressure of the championship fight at the Brazilian Grand Prix.

For fans and experts, looking at a driver's personal life can help understand their mental strength. This article connects Leclerc's engagement to his proven skill, like his record-breaking qualifying laps.

Who Is Alexandra Saint Mleux?

At 27, Alexandra Saint Mleux stands out in the worlds of art, digital media, and fashion, areas that align with F1’s global glamour. A native of France, she studied art history at L'École du Louvre, specializing in 20th-century movements. Her studies sharpened her ability to interpret modern culture and artistic expression.

How They Met

According to reports, their relationship began at Paris Fashion Week in March 2023. This was just after Leclerc's important first victory in Australia for Ferrari. First, they got a dog named Leo in mid-2023. Later, people saw them together at Wimbledon, but their relationship had actually started during an off-season trip to Paris.

They began appearing together more often. The most important event was the 2024 Monaco GP, where their first red-carpet appearance showed the world she was now a part of his life and heritage.

They enjoyed quiet dates at NBA games, a contrast to the loud F1 world. By 2025, they were sharing a home, and her calm presence at races provided support during his intense championship battle. By traveling together and sharing their experiences, they have built a strong partnership. This provides Leclerc with a stable and supportive foundation for his racing.

Engagement Announcement

The proposal, revealed on November 2, 2025, via Leclerc's Instagram, evoked fairy-tale whimsy with a personal twist. A series of four photographs captured the couple in Monaco's sun-drenched environs: Saint Mleux's radiant smile as Leclerc knelt, their embrace under golden hour light, a close-up of her emerald-cut diamond ring (estimated at 5 carats, sourced from a Parisian jeweler), and Leo sporting a collar emblazoned with "Dad wants to marry you!"—a nod to their "fur child." Captioned "Mr². & Mrs. Leclerc ," the post amassed 247,000 likes within hours, blending vulnerability with Leclerc's signature emoji-laden brevity.

The announcement resonated across F1's digital ecosystem. Lewis Hamilton commented, "Congrats brother! ," while Carlos Sainz quipped, "Finally! Welcome to the club." Tennis stars' partners, including Jannik Sinner's Laila and Tommy Paul's fiancée Paige Lorenze, echoed the joy, highlighting cross-sport camaraderie.

On X (formerly Twitter), reactions trended with #LeclercEngaged, blending euphoria ("Championship week for Ferrari—on and off track!") and lighthearted memes about Leo's matchmaking. Analysts view this transparency as strategic: In an era of mental health advocacy (post-2021 Abu Dhabi controversy), such openness humanizes drivers, potentially boosting fan loyalty and sponsor affinity.

Alexandra's Style Influence

Saint Mleux has a unique fashion sense that blends timeless elegance with a modern, eco-conscious mindset. This stylish image complements and aligns with Formula 1's own brand and future goals.

Compared to predecessors, her influence rivals Kelly Piquet's (Max Verstappen's partner) in fostering aspirational WAG archetypes, potentially amplifying Ferrari's luxury partnerships (e.g., via Loro Piana's F1 collaborations).

What’s Next for the Couple?

Leclerc is chasing the 2025 F1 title, just 19 points behind Verstappen after Mexico. Saint Mleux may become a key support in his personal life. Rumors suggest they might marry in Monaco after the 2026 season, with Leo as the ring-bearer. Her art projects could one day connect with F1 charity work. They may expand their family, but for now, they seem focused on raising Leo together as Leclerc looks toward his future with Ferrari.
