Florida Georgia Line and Sam Hunt represent at Sunday’s "Billboard" Music Awards

Courtesy Dick Clark ProductionsIf you're a Florida Georgia Line fan, you won't want to miss Sunday's Billboard Music Awards.

In addition to being the most-nominated country act with six nods, Tyler Hubbard and Brian Kelley are set to perform with John Legend. They'll do a mash-up of their nominated song “H.O.L.Y.,” along with the Oscar-winning R&B singer/songwriter's current single "Surefire." 

Even though he's not among this year's nominees, Sam Hunt will take the stage to sing his chart-topping hit, "Body Like a Back Road." It's his first major TV appearance since getting married last month. Ironically, he performed the same song at the same venue in early April at the ACM Awards, while serenading his now-wife Hannah Lee Fowler.
