It's a boy for Chris and Morgane Stapleton! Morgane revealed more details about the couple's fifth child in an Instagram post on Wednesday (May 29).

"Sweet boy ... It's hard to believe almost a month has already gone by," Stapleton writes in the caption of a photo of her newborn son in his hospital bed. "Time flies faster than I ever thought imaginable. My heart is so full!"

Morgane Stapleton first shared the news of her and her country superstar husband's new arrival on (appropriately) Mother's Day. At the time, she did not reveal the baby's sex, birthday or other details; at this time, fans have still not learned the baby boy's name.

This newest baby has four older siblings, including twin big brothers who were just seven months old when the Stapletons announced they were expecting yet another addition to the family. The musical couple are also parents to two older children, a son and a daughter.

Chris and Morgane Stapleton have been married since 2007, and are cautious to keep their children's personal information private. According to Stapleton, just because he chose to live in the spotlight doesn't mean his children should have to, and as they grow older, it will be up to them to decide what details about themselves to reveal to the public, and when.
