Kim Kardashian and Lewis Hamilton were seen taking a loved-up stroll in Tokyo this weekend to further fuel speculation over a potential romance.

The A-list duo are believed to be dating after being spotted together on two separate occasions in recent weeks, including at last month's Super Bowl in Santa Clara, California.

Rumors first surfaced when they were pictured checking into an upmarket hotel in the Cotswolds together at the end of January, and whispers of a relationship have grown louder ever since.

Now Kardashian, 45, and Hamilton, 41, have been captured again out in Tokyo, where the Formula One star is enjoying some downtime with his new flame in between the Chinese and Japanese Grand Prix.

Fan footage posted on social media shows the couple walking through the streets and acknowledging stunned passers-by.

Hamilton appeared in good spirits while out and about with the reality TV star, even waving to a fan in one photo shared online.

The Ferrari driver, who holds the joint-record for most F1 titles in history with seven, finished third in last Sunday's Chinese Grand Prix and will hope to build on his encouraging start to the season in Japan next weekend.

The race in China denied him the chance to make his red-carpet debut with Kardashian, however, who attended the Oscars in Los Angeles.

Hamilton co-produced and enjoyed a cameo role in the 2025 'F1' movie starring Brad Pitt and Damson Idris - which won an Oscar for Best Sound - but he was unable to join the cast and crew at the ceremony due to his F1 commitments.

While neither party has confirmed it publicly, Hamilton and Kardashian are understood to have struck up a secret relationship behind the scenes in recent months.

Back in January, the pair were seen arriving with a motorcade in tow at five-star Cotswolds establishment Estelle Manor, before they went to the Super Bowl together.

Hamilton was asked about the relationship by a member of the press while at the game, yet according to Sky Sports' F1 reporter Ted Kravitz, he shut it down by saying: 'It's my private life, I'm not talking about that.'
