Jason Aldean’s oldest daughter, Keely (23), is now a married woman! The hitmaker shared the news while co-hosting Country Countdown USA with Lon Helton one the weekend.

According to Aldean, his oldest daughter’s wedding took place over a year ago, and it wasn’t published, but rather done in secret.

“My oldest, Keeley, graduated from college. She got married about a year ago,” he shares.

During the conversation, Helton asked if Aldean was ready to be a grandfather and he was quick to express his thoughts.

“No, I told her to pump the brakes on that,” he shares. “Don’t be in a hurry. More for my sake, I think. But it’ll happen when the time’s right.”

The singer didn't share further details on the location of the wedding nor Keeley’s new husband.

While his daughter's Instagram is private, her profile photo shows her in a wedding dress, along with her new last name, Chastain.

During the interview, Aldean took time to share a rare update on how his other three children are doing.

Kendyl is headed to college in a few months, and his youngest two, Memphis and Navy, have been able to go out on the road with him this year.

“From the time they were two weeks old, they were on the bus and on the road,” he says. “That’s not new for them. They’re so used to it, they ask for their backstage pass and wander off on their own. They go all over and know what they’re doing.”

He went on to share that he's not his youngest two's favorite artist to play around the house: Stella Lefty is!

"I heard the song by Stella Lefty on the radio, and it wasn't two days later, my kids were running around the house singing that song," he said. "That's how you know you have a hit — when 7- and 8-year-olds are singing it."
