Carlos Sainz's girlfriend, Rebecca Donaldson, celebrated her birthday on 24 July 2025. In line with this, George Russell and Charles Leclerc's girlfriends, Carmen Montero Mundt and Alexandra Saint-Mleux, have come up with lovely messages for Donaldson.

Rebecca Donaldson is from central Scotland, and she attended the Perth Academy. She is a model by profession and is represented by Brand Model Management. She has even graced the covers of Vogue Ukraine and Marie Claire México.

In line with her success in the world of modelling, she credits her mom for signing her up for a beauty pageant at the age of 17. She said the following via the Daily Record in 2011:

"My mom entered me and I was really surprised when I found out. We had to go to rehearsals to practise catwalk type dances before going in front of four judges.."

Carlos Sainz doesn't understand Red Bull's decision not to pair him with Max Verstappen.

During the 2024 Formula 1 season, Carlos Sainz, on numerous occasions, was linked with a potential switch to Red Bull for 2025. However, it ultimately did not come to fruition, and Sainz ended up signing for the Grove-based Williams F1 team.

In line with the reluctance of Red Bull to sign him for the 2025 season as a teammate of Max Verstappen, Sainz recently said:

"The only thing I can say is I genuinely get on well with Max. This is what people don’t see from the outside. Like, we had a rivalry on our first year in Formula 1 in Toro Rosso, but it was a relatively healthy rivalry in terms of him and me, the way we used to go about racing. And now we get on really well. So, if that’s the reason I don’t understand why they wouldn’t want me next to Max, because I think we would actually be a very strong pairing in Formula 1." Via High Performance Podcast.

Carlos Sainz and Max Verstappen were teammates at Toro Rosso (Racing Bulls) during their early days in the sport. Verstappen joined Red Bull in 2016, and Sainz made the jump to Renault (Alpine) in 2017.

While Sainz has switched teams frequently in his Formula 1 career, Verstappen has stayed put at Red Bull since 2016.
