Kim Kardashian and Lewis Hamilton made their relationship Instagram official after weeks of romance rumors.

In an Instagram reel the Formula One driver posted on Monday, the reality TV star, 45, was seen sitting shotgun of his bright red Ferrari while he was driving.

Hamilton, 41, was driving around his race car at high speeds around the streets of Japan. 

He set the video to the song Victory Lap by Skepta, PlaqueboyMax and FredAgain and wrote in the caption: 'HERE WE GO AGAIN. TOKYO DRIFT VOL. III.' 

Near the end of the video, The Kardashian star could be seen sitting in the passenger seat and smiling widely after Hamilton showed off some of his driving tricks.

Kardashian recently traveled back to California for an extravagant Easter celebration with her family, but in late March, the pair were seen walking together in Tokyo.

Kardashian and Hamilton were first rumored to be dating in early February when they were seen on what appeared to be a romantic weekend trip in Europe. 

They were reportedly spotted in the Cotswolds and later traveled from the U.K. to Paris. 

That same month, they made a public appearance together and were spotted sitting together in the same VIP booth at the Super Bowl.  

In early March, they enjoyed a luxurious trip together in Utah, and at the end of the month, the pair traveled to Tokyo alongside Kardashian's kids.

Kardashian reportedly brought along her three youngest children: Saint, 10, Chicago, nine, and Psalm, six. 

Her eldest child is her 12-year-old daughter North, and Kardashian shares all four kids with her ex-husband Kanye West. 

During their trip, Kim's sister Khloe Kardashian also tagged along and brought her daughter True, seven, and son Tatum, three. 

Earlier this year, a source said that the couple have an 'intense' relationship and added that her family 'adores' him. 

'Kim and Lewis's relationship is intense, but they are both keen to keep moving forward,' an insider previously told The Sun. 

'He wants to spend as much time with her as possible, especially as he'll be back getting ready for the new F1 season in a couple of weeks.' 

The source added: 'Lewis has been in LA, spending time with Kim and her family. They all adore him, especially her mom Kris [Jenner], who has loved having Lewis around.' 

'They're all really approving of this relationship. They just want to see Kim happy.'

Kardashian and Hamilton have been friends for years, and were pictured with their then-partners, Kanye West and Nicole Scherzinger, in 2014 at the GQ Men of the Year Awards in London.

In 2015, Kardashian's ex-husband invited Hamilton to spend Easter with their family, with the rapper saying at the time: 'Lewis Hamilton's over at my house and we're playing some music in my studio.'

'We're having an Easter brunch and all of the family's there, my wife's family, my friends, everything. And everybody's like, "What is this music?" And I'm like, "It's Lewis Hamilton's music."

'They're like, "Oh my God. It's really good."'
