On April 6, Hamilton shared an Instagram video showing him driving through Tokyo in a Ferrari.

During the clip, the camera briefly pans to Kardashian seated beside him, reacting to the high-speed drive by saying, “That’s insane.”

The appearance comes after weeks of speculation about the two.

They were first linked in January after being spotted at a New Year’s Eve event in Aspen, followed by reports of them travelling together on a private jet from the UK to Paris.

Kardashian was recently in Japan with her children — North, Saint, Chicago and Psalm — while Hamilton was in the country for the Japanese Grand Prix.

Fans have also pointed to Hamilton’s recent activity on social media, including engaging with Kardashian’s posts, as further indication of a possible connection.

Neither Kardashian nor Hamilton has publicly confirmed any relationship.

However, Kardashian recently described herself as a “hopeless romantic” in an interview, adding that she would be ready when the right person comes along.
