The duo’s female half, Joy Williams, announced her pregnancy on Friday by Tweeting, “Beyond elated to share that [husband] Nate [Yetton] & I are expecting our first child in late June!!! My baby bump & I will see you on the red carpet.”
Williams, 29, and partner John Paul White picked up awards for best folk album and best country duo/group performance at Sunday’s show.
“I’m feeling butterflies but I can’t tell if it’s my baby kicking or the actual butterflies itself,” she said backstage, joking that she’s a “human bakery”. “Both sensations are really, really wonderful.”
Williams and White, who formed their band in 2008, hit the public eye when their song “Poison & Wine” was featured on Grey’s Anatomy.
The Civil Wars collaborated with the singer and composer T-Bone Burnett for “Safe & Sound,” the first song from The Hunger Games soundtrack, premiering Monday evening on MTV.
