Oh, Bey-by!

Choreographer Sarah Francis Jones went into labor while enjoying Monday’s Beyoncé concert in Los Angeles with her husband, actor Marcel Spears — giving birth to a healthy baby daughter just a few hours later.

The crazy-in-love couple charmingly documented their experience on social media, posting a reel to Instagram which showed Jones in a silver dress and headband dancing along to the music, and then having to sit down due to labor pains.

The video then cuts to Jones giving birth in the delivery room, with proud dad Spears holding their newborn, Nola, at the end.

Jones also posted another reel capturing the moment, writing in the caption, “Turns out we were having a whole baby at @beyonce bday show.”

The Post reached out to the couple and representatives for Beyoncé for comment.

On Wednesday, the proud parents told local news channel KTLA 5 that their adventure began shortly after the “mute challenge,” a fun part of the concert during the singer’s performance of the “Renaissance” track “Energy,” where everyone is expected to go silent after the line, “Look around everybody on mute.”

“She wasn’t due for another week, and so I thought maybe they’re Braxton Hicks [contractions], and I said, ‘Um, something’s happening,’ ” Jones told KTLA.

“Usually I like to dance at the concert, and I was like, ‘I think I need to sit down for a second,’ ” she added.

As the concert went on, and when they got to their car after the show ended, the papa and mama-to-be realized it wasn’t a false alarm — and that Jones was really going into labor.

“The biggest contractions were happening during ‘Virgo’s Groove,’ ” Spears said, referring to a song released on the “Renaissance” album.

Once at the hospital, Jones gave birth to a healthy baby girl.

The couple noted that they still don’t have a middle name for Nola, and are open to something “Beyoncé-like.”

They added that they decided to name their bundle of joy “Nola” because Spears is from New Orleans, and Jones wanted a name that started with the letter “N.”

Beyoncé’s Renaissance tour will wrap Oct. 1 in Kansas City, Missouri.

Jones isn’t the only one who has gone into labor while attending a concert recently.

In July, Taylor Swift fan Tori Hedges, 28, went into labor during the star’s Eras tour in Ohio.

An ambulance came to the concert site to take her to the hospital.

“We were just happy we could get down there and go, hoping that I would be able to make it, and luckily was able to make it for the most part,” the Swiftie told WKRC.

“It was literally not even 20 minutes after she got off the stage when we were leaving, going down the ramp,” explained Hedges. “That’s when I was like, ‘I think I got to go to the bathroom.’ ”
