Two identical twin sisters who are also married to identical twin brothers have announced that they are now both pregnant at the same time.
Now the foursome are getting ready to welcome 'quaternary multiples', as Brittany and Briana are both pregnant.
Announcing the happy news on their joint Instagram account, @salyerstwins, they wrote: "Guess what!!?? BOTH couples are pregnant!
"We are thrilled and grateful to experience overlapping pregnancies and to share this news with you all!
"Our children will not only be cousins, but full genetic siblings and quaternary multiples! Can't wait to meet them and for them to meet each other!"
The two couples had previously admitted they were looking to get pregnant at the same time, with Jeremy spilling the beans in TLC documentary Our Twinsane Wedding.
He said: "We want to have twins, and we want them to be born on the same day... We'll be raising our families together as well. That's something we're all on the same page about too."
Thankfully, they didn't go into any details about the specifics around simultaneous conception, which sounds very difficult to orchestrate...
The two sets of twins know that their lifestyle perhaps isn't for everyone, having accepted that they might be seen as a little 'eccentric'.
However, while their respective relationships may seem unorthodox, they've previously said there is a line - having explained there is no partner swapping between the siblings.
When asked by Fox News to identify the strangest question they get asked, Jeremy said: "We get a lot of questions about our living situation, [we get] mostly positive responses when people find out about it. We don't mind talking about it at all."
Briana added: "I would add that we totally know we are eccentric, socially eccentric.
"I would say that the one that we get a lot [is that] people always ask if we switch partners - I hope we have explained ourselves that we do not!"
As for living together under one roof? Briana said that took some getting used to, understandably.
She said: "Our first few months of marriage have been a whirlwind of fun and getting used to being married and the four of us living together, that dynamic."
Her sister Brittany added: "With all four living together under one roof, there's a lot of double dates."
Well, now I'm guessing there are going to be a lot of nappies.
