Listen to Florida Georgia Line on iHeartRadio

Florida Georgia Line's hit "Cruise" has been a huge success over the last year, and the song blew up even more after they debuted their remix with Nelly.

During the duo's performance at the iHeartRadio Country Festival in Austin, Texas, they closed out with "Cruise," and when it came time for Nelly to spit some rhymes, they rapped his verse!

Check out photos of their performance below!
