Jason Aldean and his wife and kids have welcomed an adorable new family member! Aldean's wife, Brittany, turned to Instagram on Saturday (Sept. 7) to show off their new "baby" — a sweet puppy named Saint.

"Our baby is finally here!! His name is SAINT," she writes, accompanied by a heart emoji. "And he is going to have the best life!!"

They adopted the adorable pooch from Stray Rescue of St. Louis, which is where they got the name Saint. In a video accompanying her post, Brittany Aldean says she really wanted to adopt both Saint and his littermate, but "my husband wouldn't let me."

"But he got adopted," she adds.

In the delightful video, she lifts little Saint out of the car carrier he's been traveling in and snuggles him up on her left shoulder, telling him what a great life he's going to have with her family, which includes the couple's son, Memphis, and their daughter Navy Rome, who was born in February. Aldean also has two daughters, Keeley and Kendyl, from his previous marriage.

Saint certainly won't lack for space. The Aldeans sold their massive rural estate outside of Nashville in February, and they're currently in the midst of building an even more massive mansion on a beautiful piece of rural Tennessee land.

The couple shared an early photo of the construction in March, and the massive abode looks like someone could be building a small resort from a distance. More recently, Brittany posted a photo of the construction of a mind-boggling pool that literally looks like it could be from a very upscale hotel. When complete, the pool area will include a beach entrance with lawn chairs, a tiki bar and a 60-foot water slide.

Brittany lost her longtime canine companion, Bentley, in August of 2018. She'd had him since she was 19 years old. She and Aldean have previously adopted a French Bulldog named Boss, and Brittany also brought a Pomeranian named Mia into the marriage. Aldean his adopted bulldogs of his own in the past.
