Rebecca Donaldson and Alexandra Saint-Mleux have been great companions since their Ferrari days, especially when Carlos Sainz was driving for the Prancing Horse. Sainz and Leclerc were teammates at the Italian team, and as a result, Donaldson and Saint-Mleux were often spotted spending time together at the Ferrari garage and the paddock during race weekends.

However, Sainz joined Williams in the off-season, with Ferrari replacing him with Lewis Hamilton.

Despite this, Saint-Mleux and Donaldson continue to be friends with each other. Donaldson's latest comment on Saint-Mleux's Instagram post is a testament to that.
