Hilaria Baldwin revealed the heartbreaking news that she suffered a miscarriage — her second one this year.

“We are very sad to share that today we learned that our baby passed away at 4 months,” Hilaria, who has four children with husband Alec Baldwin, announced on Instagram Monday night.

The couple were expecting a girl.

Hilaria, 35, said she learned of the miscarriage during a scan on Monday — and the news left her “devastated.”

Despite the heartache, Hilaria wrote that, “even though we are not ok right now, we will be.”

A tearful Hilaria posted a video with the announcement alongside the couple’s eldest daughter, 6-year-old Carmen.

“Thank you for saying you’re sorry, Mommy’s sad,” Hilaria tells her daughter in the clip.

Hilaria said she shared the tragic news with Carmen — and indicated she’d be sending the video to her husband.

“I told Carmen and took this so I could send it to Alec,” she said.

“I told her that this baby isn’t going to come after all… but we will try very hard to give her a little sister another time.”

Hilaria also suffered a miscarriage last April.
