Look out for that baby bump on the red carpet!

At last night's CMAs, singer Shay Mooney — who's part of the country music duo Dan + Shay — brought his pregnant fiancée Hannah Billingsley as his date, and the 25-year-old showed off her growing belly in a pale pink gown.

The couple announced the pregnancy just three weeks ago with an adorable photo on Instagram, writing, "Gonna have a new band member in the Mooney family… 2017 is gonna be the start of our best adventure yet! Mini Mooney is comin in hot."

Shay and Hannah, who's a former Miss Arkansas, got engaged in August after two years of dating. “She’s the best thing that’s ever happened to me, so I had to lock it down," the groom-to-be, 24, said at the time. "She’s my better, and much better-looking half."

We're so thrilled for the duo!
