Name change decision

In 2022, Hamilton revealed that he intended to honour his mother Carmen with an unexpected name change. The F1 legend received a knighthood in 2021 for contributions to motorsport and attended the ceremony at Windsor Castle with his mum alongside him.

Twelve months later, the racer revealed he was undertaking the process of incorporating his mother's maiden name, Larbalestier, as his middle name. Hamilton said: "None of you might know that my mum's [sur]name is Larbalestier, and I'm just about to put that in my name.

"Because I don't really fully understand the whole idea of why, when people get married, the woman loses her name. I really want her name to continue on with the Hamilton name."

As of 2025, it remains unclear whether Hamilton has successfully changed his name or not.

Mammoth net worth

Hamilton was crowned Britain's wealthiest active sports star by the 2025 Sunday Times Rich List, with a net worth of nearly £400million. The seven-time world champion is the 324th richest person in the UK, with his switch from Mercedes to Ferrari resulting in a significant increase in his net worth to an eye-watering £385m.

Following his surprise move to Scuderia, the driver reportedly rakes in £50m a year on his two-year contract, surpassing Max Verstappen's record-breaking deal of £47m annually with Red Bull.

With numerous fourth-place finishes under his belt, Hamilton could be pocketing even more than his base salary with performance bonuses not included in the initial figure.

The 40-year-old will also boost his earnings through various endorsement deals and his own enterprises, which include a streetwear line and a partial ownership stake in the NFL team, the Denver Broncos.

Toughest decision of Hamilton's life

Hamilton confessed that switching off Roscoe's life support was the "hardest decision" he has ever faced. The Ferrari ace could only stand by as the dog was placed in a coma during a battle with pneumonia and fought for four days on life support.

After the tragic loss of Roscoe, Hamilton shared the devastating news on his social media. He wrote: "After four days on life support, fighting with every bit of strength he had, I had to make the hardest decision of my life and say goodbye to Roscoe.

"He never stopped fighting, right until the very end. I feel so grateful and honoured to have shared my life with such a beautiful soul, an angel and true friend. Bringing Roscoe into my life was the best decision I ever made, and I will forever cherish the memories we created together.

"Although I lost Coco, I have never been faced with putting a dog to sleep before, though I know my mum and many close friends have. It is one of the most painful experiences and I feel a deep connection to everyone who has gone through the loss of a beloved pet.

"Although it was so hard, having him was one of the most beautiful parts of life, to love so deeply and to be loved in return. Thank you all for the love and support you've shown Roscoe over the years. It has been so special to witness and feel."
