Florida Georgia Line's Tyler Hubbard and Brian Kelley were in charge of ET's Instagram on Sunday, letting us into the lead up to the Academy of Country Music Awards.

From their rehearsal to the red carpet, Tyler and Brian took us through a day in the life of a country music star.

Their proudest moment may have been accepting Vocal Event of the Year for "This is How We Roll," featuring Luke Bryan. This marked their fourth ACM win. The duo also won Vocal Duo of the Year and were also nominated for Entertainer of the Year and Single Record of the Year. They lost Single Record to Lee Brice's "I Don't Dance."

"It's a huge honor," Tyler told ET's Nancy O'Dell at the ACM Awards. "It's very surreal for us. Just two years ago we were at the ACMs for the very first time, so to be up for [Entertainer of the Year] is unbelievable and we're happy and honored and it's very humbling at the same time."

While Tyler and Brian clearly enjoy working with each other, it's always nice to get some fresh blood in the mix. Nancy found out who they would most like to collaborate with.

"In the country world it'd be fun to do something with Garth [Brooks]," Brian said. "That'd be a dream come true. Outside of the country world, Rihanna would be amazing."
