Kim Kardashian, Khloe Kardashian Support Lewis Hamilton at Grand Prix

Kim Kardashian and Lewis Hamilton’s romance is full speed ahead. 

After all, the SKIMS founder stepped out alongside sister Khloe Kardashian at the Monaco Grand Prix June 6 to support the seven-time Formula 1 champion.

For her first paddock appearance, Kim, 45, wore a black lace bodysuit with figure-hugging jeans and black kitten heels.

Meanwhile, Khloe, 41, opted for an all-black ensemble comprised of a V-neck tank top, capris, and flip flops.

Ahead of the prestigious race June 7, Kim—who first sparked romance rumors with Lewis in January—cheered on the British racing driver during qualifying, in which he ultimately landed in the third-place position.

Though the pair have kept much of their romance private, Kim officially hard launched their relationship with a hilarious social media video June 1.

Within a carousel of photos shared to Kim’s Instagram, Lewis, 41, captured the moment when The Kardashians star nearly fell of her bike as the couple enjoyed a ride through New York City.

After she attempted to pose for a selfie with Lewis, Kim lost her balance as she let out an audible scream.
