Kim Kardashian recently cemented her bond with Lewis Hamilton's family, including his niece Willow and nephew Kaiden, during the F1 driver's summer break from racing. The Kardashians star joined her boyfriend on a tropical vacation, spending time with Hamilton's loved ones.

A photo captured Kim hitting the waves on a surfboard with Willow. An accompanying video revealed that the 45-year-old's younger children, Saint, 10, Chicago, 8, and Psalm, 7, also joined the beach excursion. Her sister, along with her children True, 8, and Tatum, 4, were also present. Other images from the island getaway included a steamy bathroom selfie of Lewis, 41, hugging a bikini-clad Kim, and a candid shot of the couple enjoying a sunset walk on the beach.

Kim captioned a post, "Somewhere over the rainbow." On his Instagram, Lewis shared photos of Kim, his niece, his nephew, and his younger brother Nicholas Hamilton. The race car driver captioned his snaps, "Only some of my Summer break. Grateful for the days away. I’m heading back to track recharged and ready."

This was not the first time Kim and Lewis blended their families for a vacation. In May, the two traveled with the SKIMS founder's children, including her 13-year-old daughter North with ex-husband Kanye West. Kim described it at the time as, "Summers at the lake with my favorite people."

For Lewis, his relationship with the All's Fair actress has only grown stronger as he pursues his eighth F1 world championship title. When his former Mercedes teammate George Russell jokingly asked if a "fast car or new girlfriend" was the key to his prosperous season so far, Lewis responded with a smile during a Q&A at July's British Grand Prix, "That's a good one." While the driver admitted his first year with Ferrari was "obviously very tough," Lewis expressed gratitude to "finally see the hard work that we've all been putting in get us back to where we want to be and of course, Kim.”
