Until 2024, Donaldson and Saint Mleux often spent time together during their partners' Ferrari stints. They were spotted with each other, accompanying their Ferrari driver partners on and off the track. However, things changed in 2025.

At the end of 2024, Sainz departed from Ferrari to make way for Lewis Hamilton, who signed a multi-year deal with the Prancing Horse. As Hamilton joined Leclerc at the Maranello-based team, Sainz moved to Williams alongside Alex Albon.

Carlos Sainz and Charles Leclerc raced together for four years at Ferrari after the Spanish driver arrived from McLaren in 2021. They were always at par and hugely competitive, unwilling to yield one's position for another.
