David Nail and his wife, Catherine, are expecting baby number three, a baby girl!
The couple revealed the news with an Instagram photo of the their 4-year-old twins, Lillian and Lawson, holding hands spinning around paired with a vague caption.
"I hope he looks at his little sister like he looks at his twin sister..." the caption read.
Catherine also shared the news on her own Instagram page with a video showing the gender reveal in the backyard. David shoots off a confetti gun, sending tiny pink papers everywhere.
The couple welcomed the twins in December of 2015 after Catherine underwent In Vitro Fertilization (IVF). Catherine and David discussed the challenges they've faced in a Youtube show called the "Fighter Series." In one episode the country singer opened up about being diagnosed with depression around the same time they got news of his fertility issues.
"It was impossible not to kind of wonder is this just in the cards for us," he said at the time. Catherine added that although the procedure was painful, "it's so worth it, and I would do it 10 times again to get what we have now."
Nail also wrote about the experience in a song called "Babies" from his 2016 album, Fighter.
The couple has not revealed the official due date of the baby girl.
