You never know what's going to happen at a Garth Brooks concert!
Garth noticed a man down on one knee proposing to his girlfriend while he was singing "Unanswered Prayers" at his last tour stop in Oklahoma and offered to pay for their honeymoon trip to Hawaii.
One thing though, he didn't ask his wife, Trisha Yearwood if it was okay to make the offer to the couple, Drew and Chelsey. She said, "Sure. But no one else can get engaged tonight."
