Brian Kelley of hot duo Florida Georgia Line married his girlfriend of seven months on Monday afternoon (Dec. 16) in Nashville. The singer had known 23-year-old Brittney Marie Cole for over three years, and once they started dating earlier in 2013, both said they "just knew."

People reports that the wedding took place at Kelley's Nashville home in front of 40 guests, including bandmate Tyler Hubbard. After an outdoor ceremony at sunset, the couple dined on tapas and planned to enjoy dancing and drinking in the 32-acre property's renovated barn. Cole is a psychology student at the University of Georgia.

"There was no official proposal or exchanging of rings," the 28-year-old Kelley says of the non-traditional courting. "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!"

When the pair first met, both were dating someone else, but they say they caught each other's eye. Cole found her dress on Etsy. It's described as a short, long-sleeved gown, which she paired with a feathered headband.

A tropical honeymoon will follow for Kelley and Cole, and they plan to expand their family quickly -- a puppy is in the plans for 2014.
