The duo will play these dates in between stops on Luke Bryan 's Dirt Road Diaries tour. Florida Georgia Line joins Thompson Square on Luke's tour through the fall.

The duo's Tyler Hubbard says, "We love bringing music and good times to our fans on the road. Knowing that they are just as excited about the shows as we are is very cool...we can’t wait to meet each and every one of you at our shows!”

In other Florida Georgia Line news, they recently scored a double-platinum certification for the #1 hit "Cruise." That means two million fans have downloaded the song since it came out last year.

"We dreamed about selling one million songs back when we first started playing together and to have now sold two million is so surreal," says Florida Georgia Line's Brian Kelley .
