Hawaii – Kim Kardashian and Lewis Hamilton are floating in absolute bliss – and they aren't keeping it a secret!

On Monday, the 45-year-old reality star shared a peek at her romantic vacay with the 41-year-old F1 racer via Instagram.

"Somewhere over the rainbow," Kim wrote beneath the photo series. The opening shot shows the couple tightly embraced, strolling along the beach.

Interspersed are snapshots of them in the waves, by the sea, and surfing.

In one photo, Lewis is seen with his arm wrapped around Kim, who's rocking oversized sunglasses and a tiny bikini, as she snaps a selfie in a mirror.

And the lovebirds weren't alone on the trip!

As Kim's post revealed, several of the Kardashian-Jenner kiddos were along for the ride, including the SKIMS mogul's children Saint (10), Chicago (8), and Psalm (7). Kim shares all three kids, along with their older sister North, with ex-husband Kanye West.

Khloé Kardashian's kids, True (8) and Tatum (4), were also pictured on the trip.

Kim and Lewis have been linked for about six months now, having first sparked romance rumors with a European getaway back in February.

Since then, the driver has clearly hit it off with her family – he even treated Kylie Jenner to a joyride in honor of her recent 29th birthday!
