Tebow was previously linked to fellow Miss Universe victor, Olivia Culpo, in 2015.
"Thank you for saying YES and making me the happiest man in the world", Tebow wrote.
Per People, Tebow, 31, secretly flew in Nel-Peters' family and her closest pals from South Africa so they could be there for the pair's engagement, along with the former National Football League pro's loved ones. Nel-Peters later attended North-West University where she earned her bachelor's degree in business management. "I wanted everything to be flawless and to go smoothly. I was excited", he said.
Demi-Leigh commented, "Any dreams I've ever had, you've exceeded them all!"
Tebow said that he hid his excitement by telling Nel-Peters that he was presenting his father with a new truck at a belated Christmas dinner.
He then got down on one knee and asked her to marry him.
Here's what we know about the future Mrs. Tebow including where you might recognize her from and how her half-sister, who was born with a physical disability, plays such a huge role in her life.
Tebow told PEOPLE about his feelings before the big moment.
"They have to really love God", he continued.
Tebow tells PEOPLE that he's looking forward to planning the wedding. "My faith is important to me - it's the most important thing - and I need to be with someone who also shares that faith".
