Tim Tebow is engaged! Tim popped the question to former Miss Universe, Demi-Leigh Nel-Peters last night at his parent's farm in Florida. He did it right before Sunset last night. How beautiful! The ring? 7.25 carats! South African singer Matthew Mole surprised the couple (after she said yes) by serenaded them. After all this went down, their families and some friends went to dinner at a club in Jacksonville.
