The couple, who have only been dating seven months, wed on Monday in an outdoor ceremony at the singer's home in Nashville.
Kelley and Cole first met each other three years ago, though both were in other relationships at the time. "She definitely caught my eye [back then]," Kelley said. "Brittney's the most beautiful woman I've ever seen. I always knew in my heart that if I were single, then I wanted a chance with her. She was my dream girl."
When the couple got together earlier this year, "we just knew that it was something real," Kelley said. "I'd never wanted to make someone mywife before. I always want her by my side."
For the ceremony, Cole, a 23-year-old psychology student at the University of Georgia, wore a short, long-sleeved dress she bought on Etsy. It's a dream dress," Cole said. "And it was a dream way to obtain it, because I didn't have to go to 6,000 bridal stores to find it."
As for the decision to keep their engagement a secret, Kelley said, "The whole process has been non-traditional. 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!"
