Kim Kardashian reportedly made an eye-watering 11,000 mile round trip just to spend 24 hours with Lewis Hamilton.

The reality TV star, 45, is believed to have flown to London on Tuesday on her private jet to spend time with her beau Lewis, 41.

Kim is said to have departed Los Angeles on Monday evening and arrived in the capital the following afternoon, UK time.

After touching down in Farnborough, Hants, she was driven to F1 driver Lewis' £18million home in Kensington.

Sources close to the mother-of-four say her strenuous trip across the Atlantic is in a bid to keep their romance alive.

An insider told The Sun: 'Lewis and Kim are two of the busiest people in showbiz, but they are determined to do everything to see each other when they have any spare time. 

'Kim spent Easter weekend with her family and then had a photoshoot in Los Angeles on Monday morning, then flew across the Atlantic to see Lewis.

'They didn't have long together because she had commitments in the US to get back to, but it was quality time.'

Daily Mail has contacted representatives for both Kim and Lewis.

The day before Kim landed in London she and Lewis went Instagram official. 

A reel shared by the Formula One driver on Monday showed Kim sitting shotgun of his bright red Ferrari while he was driving.

Lewis 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.

Kim 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. 

They 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 travelled from the UK 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.

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

A source previously said that the couple have an 'intense' relationship and added that her family 'adores' him.
