Speaking exclusively to PEOPLE at the Formula 1 team x Visa Cash App RB party in Las Vegas on Thursday, Culpo, 31, praised McCaffrey, 27, and his preparations for the 2024Super Bowl.

“I feel like it’s just a crazy moment because it’s the accumulation of so much hard work and energy. He’s such a great person, he’s such a hard worker, there’s nobody in the world that deserves it more than him,” Culpo tells PEOPLE of the San Francisco 49ers running back.

Adding that she has a “lot of nerves” and a “lot of excitement” ahead of thematchup between the 49ers and the Kansas City Chiefson Sunday, the model continues, “First and foremost we’re very grateful and I always just want him to come out healthy and happy.”

TheMiss Universehost and former winner also revealed that she’s able to talk to McCaffrey “all the time” during the run-up to the game.

“You’d be surprised, they have a lot of time where they’re doing recovery and they want to be on their phones,” she told PEOPLE. “I think social media, he tries to stay off of that, but as far as texting friends and family it’s what keeps him going.”

“So many reasons to celebrate you. Proud fiance over here,” she wrote across the clip — which appeared to have been filmed from a spot backstage — adding some sweet emoji.

Earlier this week, McCaffreypraised her for giving up “so much”during his Super Bowl run.

“She’s sacrificed so much and I think all the wives do, but it’s tough, especially in season, a lot of late nights, a lot of time at the facilities,” the sportsman told reporters of Culpo at theSuper Bowl LVIIIOpening Night event at Allegiant Stadium in Las Vegas on Monday.

“She obviously is so successful in the world right now in her career, and to see her support me the way she does it means the world to me … and hopefully I can return the favor,” he added.
