Jason Aldean Celebrates His Oldest Daughter's High School Graduation With Sweet Instagram Post

Over the weekend, 44-year-old country star Jason Aldean was among the proud parents across the country watching one of their children take a big step toward adulthood at a high school graduation.

His oldest daughter, 18-year-old Keeley Williams, earned her diploma and will be attending one of Nashville's most fertile music business training grounds, Belmont University, in the fall.

Aldean commemorated the special occasion with an Instagram post.

"Hard to believe this kid graduated from high school tonight," he wrote. "Really excited to see what the next chapter in life holds for her. Your future is what u make it, so go get em Keeley. We love you!"

It's not clear if Keeley's seeking a country music career, though it's been widely reported that she's taken guitar lessons.

When Keeley missed her prom last year because of COVID-19 restrictions, her dad and his wife Brittany threw a special, surprise event for her at their Florida home.

Keeley's one of two older daughters from the country singer's previous marriage to his high school sweetheart, Jessica Ussery. Aldean also has a 13 year old daughter named Kendyl with his ex-wife.

Aldean's first marriage lasted from 2001 to 2013.

He married the former Brittany Kerr in 2015. They welcomed their first child together, a baby boy named Memphis Aldean, on Dec. 1, 2017. Their second child, daughter Navy Rome Aldean, was born on Feb. 4, 2019.

Brittany's enjoyed her stepmom role for two teenagers.

"I do love the fact that they're a little bit older because it's so fun," she told US Weekly. "I really am starting to relate to them, especially the older one. She's going through things now that I can really relate to."

The superstar couple's discussed the possibility of either a brother for their son Memphis or a fourth daughter for Jason.

"I would love to [have more kids]," Brittany told Us Weekly in May 2020. "I've been asking him, 'What would our third baby name be?' He's like, 'Well, we don't have to worry about it because it's not happening,' but I would love another."
