Rebecca Donaldson’s Career and Background
Hailing from central Scotland, Rebecca Donaldson attended Perth Academy before building a career as a professional model. Represented by Brand Model Management, she has featured on influential magazine covers including Vogue Ukraine and Marie Claire México. Donaldson credits her mother for encouraging her early involvement in modelling by entering her into a beauty pageant at the age of 17. Reflecting on the experience to the Daily Record in 2011, she said,
“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..”
This moment marked the beginning of Donaldson’s journey into the fashion world, which has paralleled her evolving relationship with one of Formula 1’s prominent drivers.
Carlos Sainz Reflects on His Career and Red Bull Speculation
Throughout the 2024 Formula 1 season, there was widespread speculation linking Carlos Sainz to a potential move to Red Bull for 2025. Despite this, the transfer did not materialize, and Sainz signed with the Williams team based in Grove. Sainz recently expressed his thoughts on Red Bull’s hesitance to place him alongside Max Verstappen in a teammate role.
“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.”
Early in their careers, Sainz and Verstappen were teammates at Toro Rosso, also known as Racing Bulls. Verstappen advanced to Red Bull in 2016, followed by Sainz’s move to Renault (later Alpine) in 2017. While Verstappen has remained with Red Bull since then, Sainz’s career has involved multiple team changes, leading to his current position at Williams.
