Brittany, 31, shared a photo on Instagram of her family's new four-legged friend on Tuesday, August 27.
Jason, 42, and the American Idol alum rescued the pup from a stray dog rescue center.
"Y’all...we have a new baby boy? We rescued him from @strayrescuestl ?? ," Brittany wrote alongside the cute snap of herself cuddling a brown and white dog.
The former Charlotte Bobcats cheerleader continued in her caption, "His brothers and sisters were all found in a drain pipe on an extremely hot day in St Louis? There are 7 pups still waiting to be adopted."
Brittany then asked her followers to suggest names for the newest member of the Aldean family.
The puppy joins Brittany and Jason's daughters Kendyl, Keeley, Navy Rome and son Memphis.
