There's a new baby in Jason Aldean's household — and no, it's not infant daughter Navy Rome! According to a post on wife Brittany's Instagram Tuesday (Aug. 27), the Aldeans have adopted a baby boy ... of the canine variety.

Brittany shared a photo of the sweet-faced pup, a brindle-and-white cutie who appears to be of mixed breed, and explained that he was adopted from a rescue group. "His brothers and sisters were all found in a drain pipe on an extremely hot day in St Louis," she noted, adding that there are still seven other puppies in his litter waiting for good homes, should anyone else happen to be looking for a new family member.

The new dog will be a perfect companion for the kids in the house; we're betting son Memphis, who turns 2 in December, will particularly become this puppy's best buddy!

The adoption of the new dog is significant for Brittany, as earlier this month she commemorated the painful one-year anniversary of losing her beloved bulldog, Bentley. "You were the sun, the moon and all the stars. You were my first child, my first love, my first responsibility in life," she wrote as a tribute to her late pet, adding that that when the family moves into their new house, which is currently being built, she plans to plant a tree and place Bentley's ashes next to a special stone.
