Thomas Rhett and his wife Lauren Akins really shared the exciting news that they're joining in on the celebrity twin announcements-- kind of.

TR and Lauren are in the process of adopting a baby from Africa and just found out they're expecting a little one on their own, too.

While on a safari in Africa with Florida Georgia Line's Tyler Hubbard and his wife Hayley, Lauren took a pregnancy test.

She revealed the full, exciting story to People Magazine:

"When we began the adoption process, we said, 'Let's wait, let's give this adopted child his or her time with us and then we'll continue our family,' " Lauren explains. "So I was convinced it was food poisoning."

But just in case, she decided to check. Certain the result would be negative, Thomas Rhett left his wife with their friends, Florida Georgia Line's Tyler Hubbard and wife Hayley, who were on safari with them, for a treadmill workout when Lauren took the test.

Sure enough, it was positive. "I'm jumping up and down, Tyler's giving me a bear hug and Hayley's running out of their room and I'm like, 'Thomas Rhett is not even here!' "

The trio ran to the gym and blurted out the news.

"I was in complete and utter shock!" says Thomas Rhett, 26. "No one is ever prepared for something like that. It is almost like we suddenly had twins."

Thomas Rhett is about to embark on his first ever headlining tour with a little help from Kelsea Ballerini.
