Identical twins sisters married to identical twin brothers announce their pregnancies together

• Identical twins Brittany and Briana Deane Salyers, who are married to identical twins Josh and Jeremy Salyers, respectively, announced their pregnancies together on Friday.
• In an Instagram post, the two couples said they're pregnant at the same time.
• "Our children will not only be cousins, but full genetic siblings and quaternary multiples," the couple wrote.

If marrying twin brothers wasn't enough, identical twins Brittany and Briana Deane Salyers announced that they're pregnant at the same time.

On Friday, the couples posted a "Baywatch"-themed Instagram announcement. The post's caption read, "Guess what!!?? BOTH couples are pregnant! We are thrilled and grateful to experience overlapping pregnancies and to share this news with you all!"

Josh and Jeremy Salyers wore matching lifeguard outfits while Brittany and Briana posed in one-piece swimsuits that read "Baby Watch."

"Our children will not only be cousins, but full genetic siblings and quaternary multiples!" the post continued. "Can't wait to meet them and for them to meet each other!"

Identical twins share very similar DNA. This means that the babies will legally be cousins, but genetically, they'll be closer to siblings.

The couple gained popularity after they were featured on the TLC show 'Our Twinsane Wedding'

While the show focused on their wedding helped them gain popularity, both couples have long embraced their twin identities. The couples live under the same roof and are often spotted wearing matching outfits.

Josh, Jeremy, Brittany, and Briana first met at the Twins Days Festival in Twinsburg, Ohio, in 2018. Less than a year later, Josh and Jeremy proposed at the Twin Lakes State Park in Virginia.

Unsurprisingly, their wedding was themed "Twice Upon a Time" and was featured on TLC. The joint wedding featured identical twin ministers and was held at the festival where the couples initially met.

In an interview after their wedding, Brittany told People magazine that "when we have children, my and Josh's children will be genetic siblings to Briana and Jeremy's children."

"Even though they're cousins, they're technically genetic siblings," Brittany told the outlet. "We imagine it will be like two moms and two dads all raising our families together."
