Alexandra Saint Mleux, the girlfriend of Formula 1 driver Charles Leclerc, recently reacted to a social media post by Rebecca Donaldson, who is Carlos Sainz’s girlfriend. Donaldson shared photos wearing a black swimsuit as part of a collaboration with British luxury brand Jimmy Choo, known for its shoes and accessories. Saint Mleux’s response consisted of four heart-eyes emojis, showing her admiration for Donaldson’s post.
Rebecca Donaldson used her official Instagram account to showcase several images highlighting the partnership with Jimmy Choo, accompanied by a caption promoting the fashion collaboration. Alexandra Saint Mleux’s simple but supportive emoji reply underlined the positive relationship they maintain despite changes in their partners’ racing careers.
Shifts in racing teams alter social dynamics between couples
Donaldson and Saint Mleux were frequently seen together during race weekends in previous seasons when their partners, Carlos Sainz and Charles Leclerc, both raced for Ferrari. The two couples often socialized in the paddock, reflecting close ties within the team environment. However, in 2025, Carlos Sainz transitioned from Ferrari to Williams to accommodate Lewis Hamilton’s arrival from Mercedes, altering the social landscape.
With Sainz now at Williams, Donaldson has developed a friendship with Lily Muni, girlfriend of Alex Albon, Sainz’s teammate at Williams. Although the new team settings have changed how often Donaldson and Saint Mleux interact in person, sources suggest their relationship remains friendly and cordial.
