Like most expectant parents, country crooner Thomas Rhett says he feels just a little in over his head.

For the second time in two months, Rhett's family is about to grow. His wife Lauren is set to deliver their second daughter in August. The Rhetts adopted 18-month-old Willa in May. A blessing, no doubt, but a scary one and a handful!

In an interview with his label, Big Machine, Rhett admitted he has no idea what to expect after Lauren gives birth, adding that when it comes to parenting, Willa has spoiled them. "We don't have any idea what we're doing at all," the 27 year old confessed. "Willa's been home for almost a month and I feel like we kind of got spoiled on the front end because Willa sleeps like 12 hours a night, so that's not gonna happen when the newborn comes."

Rhett added that although Willa doesn't quite grasp the idea that she's going to be a big sister, he and Lauren are doing their best to prepare her for that inevitability.

"Every time Willa will go touch Lauren's stomach we'll just be like, ‘Your new sister's inside there,' and obviously she doesn't know it but we're just trying to keep saying our newborn's name and trying to get her used to the fact that there will be a sister here in about a month," he said.

Aw, bless! Something tells us they'll be just fine.
