Jimmie Allen and Wife Alexis Separating with Third Baby on the Way

Jimmie Allen and his wife Alexis have announced they're separating — and expecting another baby.

The singer, 37, shared the news with fans on Instagram on Friday, adding that he and Gale, 27, will also be welcoming their third child together later in 2023.

"After much thought and reflection in recent months, Lex & I have made the decision to separate," Allen wrote. "As we navigate this life change, we can also share that we will be welcoming another child together later this year."

"Our number one priority is and always will be ensuring that our children are healthy, happy and loved, and we remain committed to co-parenting with love and respect for one another," he continued. "In light of our growing family, we respectfully request privacy during this time."

Alexis posted the same statement to her own Instagram account.

Allen, whose new competition show My Kind of Country is streaming now on Apple TV+, is dad to son Aadyn, 8, from a previous relationship, plus daughters Zara James, 17 months, and Naomi Bettie, 3, whom he shares with Alexis.

Speaking to Entertainment Tonight's Cassie DiLaura at the ACM Awards last year, the singer said he and his wife "feel outnumbered" by their kids.

"Going from two to three is a big jump. It's cool, we love 'em and we're just definitely thankful for our kids," he said.

Asked about the possibility of having another baby, Allen replied without hesitation, "Oh, I am done."

Allen later clarified his comments about "retiring" from having more kids on an episode of PEOPLE's podcast PEOPLE Every Day.

"It was actually [Alexis'] idea," Allen said of staying put with three kids. "Cause when it comes to babies, you know guys, we got the fun part ... women gotta carry the baby. Give birth to the baby. And 'cause she's told [people] before she doesn't mind giving birth, it's the pregnancy part that's normally gonna be hard on her."

"But I'm cool if she's done. My jerseys are retired, but then we did talk about maybe in a couple years having another one, but we'll kind of just see. Whatever happens, happens," added Allen.

Both natives of Milton, Delaware, the couple met through a relative in the spring of 2019 and began dating. By that summer, they were engaged.
