Joel Burger and Ashley King announced their engagement next to a Burger King sign in Illinois, US, and the story was reported in the local paper.
Burger King's PR team swiftly caught wind and launched a Twitter campaign with the hashtag #BurgerKingWedding to find the happy couple. The chain then offered to pay for their wedding.
A spokesperson told The Mirror: "When we heard about the happy, Burger-King couple, we felt an overwhelming urge to celebrate their upcoming marriage.
"On so many levels it felt like fate. They found each other and their story found us."
