Lewis Hamilton and Kim Kardashian’s rumoured relationship appears to be growing stronger with each passing day.

According to Us Weekly, the 41-year-old Formula 1 world champion seems to be on cloud nine, reportedly convinced that he has finally found a compatible partner in the 45-year-old reality star.

"They are going strong and really happy. Lewis is head over heels and those closest to him believe he has finally met his match," an insider told the outlet.

The source added, "He has waited over a decade for his dream girl and is crazy about her."

The couple have been going the extra mile for each other and making time despite their busy schedules, with Hamilton frequently connecting with Kardashian via FaceTime from the "paddock" during his demanding F1 calendar.

Fully aware of the British racing star’s professional commitments, the SKIMS founder is said to be "incredibly supportive."

Explaining the strong level of understanding in their romance, the tipster noted, "Because their relationship started with a friendship first, those closest to them believe this could be endgame for them both."

Lewis Hamilton and Kim Kardashian’s relationship timeline

The pair have known each other since at least 2014, having crossed paths at several events over the years.

Their dynamic seemingly shifted earlier this year when they were seen spending time together at Estelle Manor in Oxfordshire, England.

Hamilton and Kardashian further fuelled the relationship buzz when they were later spotted together at a hotel in Paris, at this year’s Super Bowl LX, and in Arizona, reportedly spending time to "really get to know each other."
