Jen Affleck and Zac Affleck celebrated a family milestone — their eldest daughter’s 5th birthday — hours after their divorce news made headlines.

The “Secret Lives of Mormon Wives” co-stars each gave glimpses of Nora’s festivities via Instagram Stories on Wednesday.

“I can’t believe she’s already 5,” Jen, 27, captioned a sweet snap of the little one posing beside a new bike in a streamer and balloon-decorated kitchen.

Zac, meanwhile, shared a video of Nora blowing out candles on a birthday donut while one of her siblings — brother Lucas, 3, and sister Penelope, 1 — played with a balloon in the background.

“Happy birthday Rara!” the DadTok member, 30, wrote. “I hope all your dreams always come true.”

It is unclear whether Jen was present in the footage — but she was noticeably absent from Zac’s Reel documenting a theme park trip with Nora.

“Happy Birthday to my baby girl!” he wrote Wednesday. “You have the biggest heart and make everything feel a little extra magical. I love you.”

Nora was born in November 2021, two years after Zac and Jen tied the knot.

Lucas was born in July 2023, followed by Penelope in July 2025 — and the reality stars announced in June that they have another baby on the way.

“Chapter four,” the pregnant star wrote alongside her Instagram baby bump debut at the time — and, on Wednesday, she posted new ultrasound photos with a heart emoji.

When Jen filed for divorce in Utah on Tuesday, she submitted a proposed parenting plan.

A source told People the exes “are staying focused on preparing for the baby and supporting their kids” while navigating their split.

Last year, Jen gushed to Us Weekly that her and Zac’s marriage was “stronger than ever.”

The “Dancing With the Stars” alum said, “Sometimes you go through a rough patch and for some people it’s the end and it ends with divorce and for other people they fight through it and it ends up being a blessing in disguise.”

Their relationship, notably, has been documented on “SLOMW” for four seasons since 2024 — and news broke in April that they are part of the “SLOMW: Orange County” cast, premiering Nov. 12.
