Olivia Culpo takes the plunge in strappy one-piece swimsuit

Olivia Culpo’s looking white-hot.

The style star sizzled in a plunging one-piece from Cult Gaia on Instagram Thursday during a romantic road trip with boyfriend Christian McCaffrey.

Captioning her sexy photo carousel with a single white heart emoji, Culpo accessorized with a broad-brimmed hat while posing in the desert during a stay at the luxury Amangiri resort in Utah — a favorite of fellow influencers Kim Kardashian and Kylie Jenner.

The Rhode Island native’s famous pup, Oliver Sprinkles, sat by her side while she posed.

“CMC is one lucky guy,” one commenter quipped, referencing San Francisco 49ers running back McCaffrey.

Another fan raved, “CMC is a great photographer!” as a third noted, “Mcaffrey [sic] winning on and off the field.”

Olivia, 30, started dating the 26-year-old football player in May 2019; the former Miss Universe was previously linked to Nick Jonas.

“R u joking LMAO who looks like this in the middle of the desert,” another of Culpo’s followers commented on her latest pics from her trip.

Another raved, “Perfection. I’ve never seen someone as gorgeous as you!”

Culpo and McCaffrey have been sharing “road-trip shenanigans” throughout their getaway.

Earlier this week, the model got into the Western spirit with a chic all-black outfit that included a cowboy hat and boots.

“Wide open s p a c e s,” she captioned the tableau.

We can’t wait to see where the couple head off to next.
