Shay Mooney and his wife Hannah are going to be parents again!

On Monday, July 29, the country star, 32, and his wife Hannah shared that they are expecting their fourth baby together, announcing with a video on Instagram. In the sweet video, Mooney and Hannah begin by sitting together on a couch, joined one at a time by each of their kids.

Hannah, 33, then leans over and shows off a positive pregnancy test, smiling as their family laughs together. "1, 2, 3, 4…." they wrote in their joint caption.

The couple is already parents to sons Asher James, 7½, Ames Alexander, 4, and Abram, 18 months.

In January 2023, the Grammy winner announced that he'd welcomed his third baby with his wife, sharing a video on Instagram of him singing to the newborn.

"Grateful doesn't begin to cover it ❤️," the father of three wrote.

Sharing the same video on her own account, Hannah wrote, "First song sang to the newest family member… Abram Shay, you're so loved and so prayed over, baby boy. Thankful for all that God has done for us this week 🤍."

The musician and former Miss Arkansas wed in October 2017, about nine months after Asher's birth. They later revealed they had actually tied the knot privately in 2016.

The then-infant was carried down the aisle at the ceremony, looking dapper in a baby tuxedo. Mooney's bandmate Dan Smyers and guitarist Justin Richards served as groomsmen.

Among the duo's hits is 2017's "When I Pray for You," an emotional track about becoming a dad. Mooney opened up to PEOPLE about the meaning behind its sweet lyrics, which include, "I talked to God about you / And I ain't even met you yet / Everybody's waitin' on you here / I can't wait to feel your heartbeat when I lay you on my chest."

"I was about to have my kid [when we worked on the song], so a lot of emotions were stirring around," he told PEOPLE in 2017. "We were in the room with a couple other dads that had just become new dads."
