It’ll be a girl!

Thomas Rhett and his wife, Lauren Akins, announced the sex of their baby on the way on Saturday night with a special cake decorated after the lullaby, “Twinkle, Twinkle, Little Star.”

Lauren, 27, took to Instagram to share a photo of the cake, complete with a gold crescent moon, gold stars, blue and pink frosting, as well as the first lyrics of the lullaby.

“…how we wonder what you are…” guess what we’re doing tonight 🙂 @crumbdelacrumb,” she wrote.

Hours later, the couple each shared videos of the reveal, which featured the country star, 26, cutting into the cake to discover the color pink.

The two received an ultrasound on Thursday and celebrated by going to get a sex-reveal cake. “Me and Lauren just did an ultrasound, and she is making me wait and her for us to find out if it’s a boy or a girl. What do y’all think?” Thomas Rhett said in a video he posted on Instagram.

The couple revealed in February that they were expecting a baby and adopting from Africa. They kept the happy news under wraps until Lauren was past her first trimester, and until they were far enough into the adoption process to feel confident it would work out.

But it hasn’t been an easy secret to keep, especially when the couple attended the Grammy Awards. “It was almost impossible to not mention it during interviews on the carpet,” Thomas Rhett told PEOPLE, who was nominated for best country song for “Die a Happy Man.”

“To say that we’re excited to finally be able to talk about it is an understatement,” Lauren said.
