While some F1 driver relationships dominate headlines, others are much more low-key. Such is the case for Monacan racer Charles Leclerc and his girlfriend, Alexandra Saint Mleux, who share one of the buzziest (yet most private) F1 romances. Rumors of their relationship took off in early 2023 when eagle-eyed fans spotted the two together at Paris Fashion Week. Not long after, Leclerc confirmed that he was in a relationship. Although they rarely post each other on their social media pages, they're now frequently seen at events together. Most importantly, though, they adopted a dog in 2024—a long-haired dachshund named Leo—who has become an F1 celebrity in his own right. (Need proof? He's amassed nearly 200,000 followers on a fan-made Instagram account.)
