The competition for Best Duo / Group Performance was tight, but Little Big Town emerged as the winner, for "Girl Crush."

Karen Fairchild, Kimberly Schlapman, Jimi Westbrook and Phillip Sweet took the stage with huge grins on their faces. Fairchild took the mic first, saying, "I'm shaking!"

The group all voiced their agreement and then, they collaboratively thanked a whole lot of people. Schlapman said, "Thank you, the beautiful writers of this gorgeous song, Hillary Lindsey, Liz Rose and Lori McKenna -- thank you for bringing us to this big ol' party." She also went on to thank Jay Joyce, their label, their radio team and others.

"And the fans, for sticking with the song," Schlapman interjected, alluding to the fact that "Girl Crush" became embroiled in controversy, and yet LBT's fans helped it crush records and be earn double-platinum status.

"This is incredible," Sweet concluded. "We are all so happy. We love y'all so much."

Other nominees for Best Country Duo / Group Performance included the Brothers Osborne's “Stay a Little Longer,” Joey + Rory's “If I Needed You,” Charles Kelley's “The Driver" (feat. Dierks Bentley and Eric Paslay) and Blake Shelton's "Lonely Tonight" (feat. Ashley Monroe). The 2015 winners in the category were the Band Perry, who won with "Gentle on My Mind," which is off of Glen Campbell‘s I’ll Be Me soundtrack.
