Here's the series of photos she uploaded as a post on Instagram:
Carlos Sainz and Rebecca Donaldson started dating each other in early 2023. This was a couple of months after the former Ferrari driver parted ways with Isa Hernaez, a Spanish journalist. On the other hand, Donaldson dated American TV personality Scott Disick, but they broke up in mid-2022.
After nearly seven years of relationship with Hernaez, Sainz fell in love with Donaldson, and made their first public appearance in Milan, Italy, in June that year. A couple of months later, the couple appeared together at a golf course in Amsterdam, Netherlands, again, and this cemented their status as a couple.
Sainz and Donaldson's relationship seemingly matured when the Spanish driver underwent an appendicitis surgery in early 2024. During this time, Donaldson reportedly stayed with the F1 driver at his home in Madrid, Spain, to take care of him.
As of the mid-2025 season, Donaldson and Sainz are one of the most renowned F1 couples, and often make paddock appearances together.
