The Secret Lives of Mormon Wives star Jen Affleck is pregnant with her fourth child.

The reality star and influencer took to her Instagram page to share the happy news that she and husband Zac will be adding to their family with another baby.

She wrote: "Chapter Four!"

Jen, 27, also shared a slideshow of snaps of herself showing off her growing bump, and wrote on her Instagram Stories that they will soon have "one more little soul to love".

Zac also shared Jen's post on his Instagram Stories, adding a string of red love heart emojis.

Her The Secret Lives of Mormon Wives co-stars were quick to congratulate Jen, with Jesi Draper writing: "So happy for you, love you!"

Miranda Hope added: "Glowing, Jenny."

While the Mormon Wives' Orange County spinoff cast member Avery Woods commented: "Can't wait to see you as a mum of 4!!"

Jen, who also appeared on TV talent show Dancing With the Stars, is already mum to four-year-old Nora, two-year-old Lucas and daughter Penelope, whose birth was announced in July 2025.

News of her fourth pregnancy comes after Jen opened up to People about her hopes of having a big family in the future.

She said: "Having been raised with numerous foster kids, I've always dreamed of a big family, and seeing that dream come true is both exciting and fulfilling.

"It can be daunting to think about raising [babies] while pursuing my career, but I want to show women and mothers that they can achieve anything they set their minds to, no matter how unrealistic it may seem."

Jen and Zac first met on the Mormon dating app Mutual in 2018 and went on to tie the knot the following year.

Their marriage hasn't been without its difficulties though, with fans recently speculating the pair could be having some issues when Jen was seen without her wedding ring in an emotional TikTok video in April, in which she discussed her "next chapter".

She said in the clip: "In the last two to three years, so much has happened. Between two babies, reality TV show, Dancing With the Stars, moving, identity, faith, life crisis, I'm very hopeful for this next chapter of my life."
