Alexandra Saint Mleux, the girlfriend of Formula 1 driver Charles Leclerc, recently reacted to a social media post by Rebecca Donaldson, partner of fellow F1 driver Carlos Sainz. Donaldson shared a series of photos wearing a black swimsuit as part of a collaboration with the British luxury fashion brand Jimmy Choo. Saint Mleux responded to the post by commenting with four heart-eyed emojis, showing her admiration for Donaldson’s stunning look.
Rebecca Donaldson used her official Instagram account to present the photos, which highlighted the elegant offerings of Jimmy Choo, known for its handbags, shoes, fragrances, and accessories. Alexandra Saint Mleux’s simple yet warm emoji reaction made a quiet statement of support and appreciation between the two partners of prominent F1 drivers.
Changing dynamics within the Ferrari and Williams garages
In previous seasons, Alexandra Saint Mleux and Rebecca Donaldson often spent time together during race weekends, as their partners, Charles Leclerc and Carlos Sainz, were teammates at Ferrari. The four were frequently seen together, enjoying moments off the track. However, the start of the 2025 season brought significant changes to this dynamic.
Carlos Sainz moved to the Williams team this year to make way for Lewis Hamilton, who joined Ferrari from Mercedes. Due to this shift, Donaldson and Saint Mleux haven’t been spotted together at the Ferrari garage recently. Instead, Donaldson is now closer to Lily Muni, partner of Alex Albon, Sainz’s new teammate at Williams. Despite these changes, the relationship between Donaldson and Saint Mleux remains friendly and respectful, suggesting a lasting camaraderie beyond the professional shifts in F1.
