Olivia Culpo and boyfriend Christian McCaffrey have 64 million reasons to celebrate.

On Monday, the 27-year-old girlfriend of the Panthers running back popped champagne after news emerged that McCaffrey inked a four-year, $64 million extension with the Carolina Panthers. McCaffrey, 23, is now the highest-paid running back in the league based on the annual $16 million average.

Culpo’s sister Sofia, who had been quarantining with the couple, posted clips of the Sports Illustrated stunner with the bubbly on her Instagram story.

First linked last spring, Culpo and McCaffrey have been enjoying their time together at home with loved ones, which also included a color-coordinated Easter photoshoot over the weekend.

“Happy Easter from our quarantine crew to yours,” Lisa McCaffrey, Christian’s mom, shared on Instagram as she and Culpo posed in pastel-hued sports bras and leggings.

Culpo also shared the same snap with a message to her followers.

“Happy Easter everyone 💜💜 Trying to make the most of a different feeling Easter today and feeling very grateful for my quarantine squad,” the model began. “I know there are a lot of people out there spending this holiday away from close friends and family and missing them so much. Sending everyone a little extra love today. You’re not alone and this too shall pass.”
