The ACM Awards featured a pretty amazing lineup of performers [1] on Sunday night, but they saved the best for last. A duet between Florida Georgia Line and the Backstreet Boys of their hit "God, Your Mama, and Me" [2] had everyone in the audience feeling emotional, but it was the next song that ensured the country music show went out with a huge bang. The country duo helped BSB perform their iconic song "Everybody (Backstreet's Back)," and it brought the house down. Their upcoming tour together [3] better get to our city ASAP.
