Kim Kardashian and Lewis Hamilton are hitting the gas on their relationship status.

The reality star, 45, and Hamilton, 41, went Instagram official on Monday, April 6 in a new Instagram Reel from the Formula One driver.

The two are seen on a high-speed drive in the video, which showed him whipping around in his Ferrari F40 at the Daikoku Parking Area in Tokyo, Japan.

“HERE WE GO AGAIN  TOKYO DRIFT VOL. III,” Hamilton wrote in the caption of the Reel, which was set to the song “Victory Lap” by Skepta, PlaqueboyMax and Fred Again.

At the end of the video, Kardashian can be seen in the passenger’s seat wearing a white turtleneck top. When the camera approached her in the car, the mother of four said, “That’s insane,” after her joy ride with Hamilton.
