FANS shared their theories on a new baby Duggar, after noticing a growing "bump" on Josiah's wife Lauren.
The Counting On stars already share one daughter Bella, who turned one in November of last year.
Josiah, 24, and his wife Lauren, 20, attended Jed Duggar's wedding last Saturday in Arkansas, where they all gathered for family photos during the event.
A fan snagged one of the pictures and then took to Reddit to share their find.
Alongside the large Duggar reunion, they wrote: "BTS Photos from Kelsi Jo Photography- the photographer at Jed's! wedding.
"I can't imagine having this many people in my family. It would be *so* overwhelming."
Others took the liberty of zooming in on the family photo, where they noticed Josiah, Lauren, and Bella in the front and center.
Fans were shocked as they believed the young mom to be sporting a new baby bump.
"Took this screenshot from the Jedding photographers IG - possible Siren pregnancy?" one wrote, after focusing in on the mom of one in a floor-length purple dress.
"Lauren is tiny so she probably shows early. This definitely looks like a bump to me," another speculated, adding: "If not, that is some serious bloat (she could've eaten gluten?) and a bad angle."
"I wouldn't be surprised if she is tbh," a third agreed, continuing: "It's almost their 3rd year anniversary. But I wouldn't be surprised if she doesn't announce it by then."
A fourth replied shortly: "Lauren definitely looks pregnant here."
The Spring has brought a series of Duggar weddings along with it, as Jed married his fiancée Katey Nakatsu earlier this month.
Their ceremony came just weeks after the TV personality's younger brother Justin, 18, married his own sweetheart.
Jed's parents Jim Bob and Michelle, attending the wedding, along with Joy-Anna Duggar and her husband Austin Forsyth.
The Arkansas native's twin brother Jeremiah took on the role of Best man, and Katey's sister stood as the maid of honor.
The couple stirred some controversy when the bride recited the words: "I will submit to your authority as you submit to Christ," during the ceremony.
Their marriage also came as a bit of a shock, as their entire engagement was kept secret and out of the public eye.
The Youtube channel Without A Crystal Ball claimed that Jed had been “courting a woman” for “quite some time.”
An insider told the outlet: “Literally no one knew about this until they got the invitation.
“Family and friends were stunned that not only was Jed dating but that he was engaged and getting married in two weeks.”
Last Fall, Jed confirmed that he “had a lady," though he didn't open up about the matter further, until painting a Halloween pumpkin with the name “Katey” for the holiday.
