Jason did explain the inspiration behind his son's name to Country Countdown USA, saying, he's "always been a big Elvis [Presley] fan." The "King of Rock and Roll" lived in the famous Graceland estate in Memphis, so it's easy to see where Aldean got the idea.

Not too long ago, Brittany posted a sweet Instagram pic of her son. "How's my little pumpkin pie 14 months already," she captioned her post. 

The two lovebirds have been married for a little over three years now, and have two kids together. Aldean has two daughters, Keeley and Kendyl, with his ex-wife Jessica Ussery.

With the addition of Navy Rome, they're now a family of six!

Congrats to Jason and Brittany on their little bundle of joy.
