Most Florida Georgia Line fans didn't even realize singer Kelley had a girlfriend, so they were extra shocked on Dec. 16, 2013, when he announced he'd married longtime love (and student) Cole that afternoon at his Nashville home. "The whole process has been non-traditional," Kelley told PEOPLE of the surprise nuptials. "There was no official proposal or exchanging of rings. We had just fallen in love, and I knew I couldn't live without her. It sounds like a terrible cheesy movie, but when you know, you know!"
