For years, the Monégasque F1 sensation and his art-and-fashion-savvy partner have played out a romance that feels cinematic yet grounded. Charles Leclerc, driving for Ferrari F1, is known for speed, precision, and focus. Alexandra Saint Mleux, a French influencer, model, and art-history graduate, brings creative flair and a warm presence. Together they’ve built something that looks as if it could be a scene in slow motion; one part grand prix, one part private dinner by candlelight.
On November 2, 2025, the couple shared their engagement through a series of photos that felt both intimate and intentional. Roses shaped into a heart framed the scene, candles glowed in the background, and their dachshund Leo made his star appearance with a tag that read, “Dad wants to marry you.”


It was a moment that felt natural yet full of meaning. A Formula 1 driver known for precision and a woman with an eye for beauty came together to create a setting that reflected who they are. You can almost sense the laughter, the planning, the excitement before the photos were taken. The proposal reflected love in its most genuine form. It felt real, personal, and beautifully sincere.
Alexandra Saint Mleux’s engagement ring
Charles Leclerc’s engagement ring to Alexandra immediately drew attention for its understated yet magnetic presence. From the photos, it appears to be an oval-cut solitaire diamond resting on a slender pavé band, likely set in platinum or white gold.
The diamond itself seems generous in size, somewhere around five carats, catching the light in that graceful, confident way that never feels overworked. The oval cut elongates the finger, while the pavé accents add a gentle shimmer that moves with every gesture. It feels tailored to Alexandra’s own aesthetic; soft, refined, and composed, much like the way she’s carried herself beside Charles over the years.

Why it resonates
Oval cut engagement rings have a kind of beauty that feels easy and unforced. They shimmer with every movement, their soft curves flattering the hand in such a graceful way. Maybe that’s why they’ve become one of the most loved shapes today. They feel romantic, natural, and a little bit modern all at once. In Charles Leclerc’s proposal ring, the oval cut feels like the perfect reflection of them: refined, genuine, and full of warmth.
