Dan + Shay singer Shay Mooney and his wife, Hannah, have announced that they are expecting their second child. The couple revealed online on Wednesday (Aug. 21) that they are expecting another boy.

The singer posted a series of adorable pictures of the couple's 2 1/2-year-old son, Asher James, to Instagram on Wednesday afternoon, accompanied by a video in which the diaper-clad youngster proclaims, "I'm having a baby brother!"

The news comes at the same time that Dan + Shay have landed their most recent No. 1 hit single, "All to Myself."

"Celebrating a number 1 with baby number 2!" Mooney writes to accompany the news. "Hannah and I have been dying to share the news. We thought for sure we’d be announcing a baby girl, but God has other plans for the Mooney’s. Found out today we’re having a BOY! Bout to be a new duo in town."

The 27-year-old Dan + Shay singer and the former Hanah Billingsley welcomed Asher James in January of 2017, and they married in October of that year. Billingsley is a former Miss Arkansas.

She turned to her own Instagram on Wednesday to share the happy news, posting the same pictures and writing, "We have cried and laughed all morning (I thought for sure it was a girl)! We are over the moon and can’t wait to see this precious guy be the sweetest big brother, early next year!"
