A list of Florida Georgia Line's recent collaborators includes Bebe Rexha, the Chainsmokers and the Backstreet Boys. Could Rihanna be next?

If the duo had their way, they'd land a collaboration for their next studio album. Tyler Hubbard and Brian Kelley talked to Taste of Country prior to their headlining performance at the 2018 Taste of Country Music Festival on Friday (June 8) and shared that Rihanna and Bruno Mars are dream collaborators.

Thus far, only a collaboration with Jason Aldean is confirmed for the fourth FGL studio album, and the duo say the song will really surprise their fans — it's something edgy even by their standards. "Simple" and "Colorado" are the two new songs they played during a 75-minute-long set at ToC Fest.

Additionally, Hubbard shared his No. 1 dad habit and how he wore a disguise to watch Garth Brooks and Keith Urban alongside general admission fans at Stagecoach Festival in April. The country superstars are still learning from those who came before them.

"I think you can learn something from anybody and everybody," Kelley admits.

The duo headlined the first night of the 2018 ToC Fest, closing a wild day that included cross-genre sets from Dustin Lynch, Kane Brown, Devin Dawson and Jimmie Allen. Day 2 will include finishing sets from Justin Moore and Eric Church.
