Olivia Culpo Teases Wedding with Christian McCaffrey, 'Now Let's Get Married!'

Sounds like wedding bells will soon be replacing the ref's whistle for Christian McCaffrey ... 'cause the NFL star's fiancee Olivia Culpo just made it clear she's ready to tie the knot!

The former Miss Universe, wearing a white dress, shared photos Friday on social media, along with a caption reading ... "Thanking God for a healthy season and for putting my best friend on this earth. Now let’s get married!"

You can see Culpo, 31, with the 49ers running back and their dog, Oliver Sprinkles, on a waterside balcony ... with both of 'em rocking white attire.

Of course, it's unclear when the couple -- who got engaged last April -- are going to say their "I dos" ... but it certainly feels like it'll be soon.

In fact, McCaffrey, during the lead-up to Super Bowl LVIII, opened up about the "hell of a job" Culpo has been doing planning the event.

"It's been going really well," the 27-year-old said, "and I'm sure you guys will see plenty coming soon."
