She added that it feels like "we have been hiding this secret for an ETERNITY.

"And I’d like to apologize to everyone I’ve canceled on, said no to or just been MIA, but for a second there I wasn’t sure if I was pregnant or just puked for a living. But she’s soooo worth it. We are SO excited! & if you need TR you can find him in the camping section at REI buying dude things.......jk, he’s excited too."

Rhett and Lauren, both 29, have previously opened up about their fertility struggles and decision to adopt Willa Gray from an orphanage in Uganda.

The couple had been struggling to get pregnant and at the same time, they were working Christian charity 147 Million Orphans. When they met Willa, they decided adoption was the right choice for them.

"All orphans have heart-wrenching stories, but it felt like this specific baby was ours. I think that the Lord knew what he was doing when he did not let us get pregnant," Lauren told People in 2017 shortly after bringing Willa to their Nashville home.

"I don’t think anyone can fully prepare you for the journey of adopting someone, especially from a third-world country where there are so many different laws," Rhett told the magazine at the time. "Every day you wake up with a whole new set of challenges that you never even heard of."
