See Jason Aldean’s Baby Boy, Memphis, Take His First Steps!

There are few milestones more exciting for parents than when their baby takes his or her first, faltering steps — so, of course, Jason Aldean's wife Brittany was over the moon thrilled to share a video of the couple's son, 10-month-old Memphis, doing just that.

In the video, shared on Brittany's Instagram account, Memphis steadies himself a bit shakily but confidently, then totters toward a stuffed bulldog held out to him.

"He's getting so big, I can't take it," noted Mom, adding that she was happy Memphis was "walking toward Bentley" — referring to her real-life pet bulldog who passed Aug. 4. The dog was "my little chunky companion since I was 19 years old," Brittany explained.

Aldean and his wife welcomed son Memphis in December of 2017, so the newly ambulatory little guy is marching fast on his way to his first birthday. While he already has two big sisters (from Aldean's first marriage), he'll soon have some company that's a little closer to his size, too: The couple shared in July that they were expecting again, and this time it's a baby girl.

Just one day after revealing her pregnancy, Brittany let fans in on another huge project: She and Jason are selling their current residence and building their dream house on a piece of land in Tennessee, in order to accommodate their growing family for years to come.
