Mormon Wives star Jen Affleck files for divorce while pregnant.

'Secret Lives of Mormon Wives' star Jen Affleck has filed for divorce from her husband, Zac Affleck, after seven years of marriage.

She is eight months pregnant with their fourth child.

The divorce petition was filed Tuesday, November 3, in the Fourth Judicial District Court in Provo, Utah.

Jen Affleck, 27, listed the date of separation as June 1, 2025, according to court documents obtained by ABC News.

The couple has three children together: daughters Nora, 5, and Penelope, 16 months, and son Luca, 3.

Jen announced she was expecting their fourth child in June 2025, posting photos in a yellow halterneck dress with the caption “Chapter Four.”

The filing comes just one day before the premiere of the Hulu spin-off 'The Secret Lives of Mormon Wives: Orange County,' in which Jen appears.

She and Zac relocated from Utah to Orange County in recent years.

The news also broke on Nora’s fifth birthday, which both parents celebrated on Instagram Stories.

Zac posted photos of his daughter with the caption: “This girl turned 5 today… She truly is the sweetest girl with the biggest heart. So lucky to be her dad.”

Jen shared a photo of Nora with a new bike, surrounded by balloons, writing: “I can’t believe she’s already 5.”

The couple met in 2018 on the Mormon dating app Mutual.

Jen was 18 at the time; Zac was 21.

They got married in 2019.

Jen rose to fame on social media as a young Mormon mother and became part of MomTok, a viral group of Utah-based mom influencers.

In 2024, she was cast in Hulu’s reality docuseries 'The Secret Lives of Mormon Wives,' which followed the dynamics of the MomTok group.

The show’s first season revealed serious cracks in Jen and Zac’s relationship.

They argued about Zac’s gambling and Jen’s choice to potentially attend a Chippendales show in Las Vegas.

Viewers watched them nearly call it quits before deciding to keep working on their marriage.

After season 1 aired, they briefly separated.

That separation became a major plotline in season 2, and during that time Jen discovered she was pregnant with their third child.

In September 2024, after the series premiered, Jen told Us Weekly: “Ever since we finished filming, we’ve been doing nonstop therapy and it’s been great.”

She added: “So if anything, [watching the show] is just going to be exposure therapy at this point. We’ve healed and now we’re ready to talk about it once it comes out.”

Also in September 2024, Jen posted a long Instagram tribute to Zac, praising his support.

She wrote: “Zac bought me my first laptop when he had $10 in his bank account.”

“When I shared my dream of running a marathon, he trained alongside me and ran it with me.”

“I told him I wanted to start my videography business, so he saved up money and bought me my first camera.”

“When we were expecting our first baby, I wanted a place to call home, so he worked hard, saved up, and bought us our first house.”

She concluded: “He gave me both stability and freedom, which allowed me to post videos online and launch my career on social media.”

Jen added: “Is Zac perfect? No. Does he have flaws that we’ve needed to address? Yes. But I can confidently say he’s always supported and believed in me more than anyone else.”

In a 2024 Instagram post, Jen reflected on their marriage, writing: “We were just kids when we got married. Young, naive, and inexperienced, we truly had no idea what we were getting ourselves into.”

She continued: “We didn’t always see eye to eye, and a lot of times, we still don’t. But that’s what marriage is, we keep trying.”

“I couldn’t have done it without Zac,” she added.

The couple continued to appear together on seasons 3 through 5 of 'The Secret Lives of Mormon Wives.'

Jen also competed on season 34 of 'Dancing with the Stars,' and Zac was seen in the audience and on social media supporting her.

ABC News has reached out to representatives of Jen Affleck for comment on the divorce filing.

Jen is scheduled to appear in the 'Mormon Wives' spin-off 'The Secret Lives of Mormon Wives: Orange County,' which premieres on Hulu on November 12.

The Walt Disney Co. is the parent company of ABC News and Hulu.

Divorce proceedings in Utah typically involve a 90-day waiting period after filing before a decree can be finalized.

Because the couple has minor children, the court will require a parenting plan and child support arrangement as part of the final divorce order.

The filing lists the separation date as June 1, 2025, meaning the couple has been living apart for roughly five months.

It remains unclear whether the divorce will be contested or if the couple has reached a private agreement on custody and property division.

Neither Jen nor Zac has issued a public statement about the filing as of this report.

The couple’s relationship timeline — from their 2018 meeting on Mutual to their 2019 wedding to their public struggles on reality TV — has been closely followed by fans of the show.

Their marriage was a central narrative across all five seasons of 'The Secret Lives of Mormon Wives.'
