Talk about a glowing mama-to-be! Carrie Underwood -- who announced on Wednesday (Aug. 8) that she is pregnant with her second child -- maintained her amazing sense of style throughout her first pregnancy in 2014 and early 2015.

Before giving birth to her first child, son Isaiah, in February of 2015, Underwood put her best (high-heeled) foot forward while waiting for her and husband Mike Fisher's new addition to arrive. From the 2014 Global Citizen Festival -- one of her first performances after her Labor Day pregnancy announcement -- to her multiple wardrobe changes while co-hosting the 2014 CMA Awards, Underwood remained on top of the best-dressed lists.

During her first pregnancy, Underwood stayed in the spotlight, too. From her win at the American Music Awards to her duet with Michael W. Smith at CMA Country Christmas, to her performance at the American Country Countdown Awards, the Oklahoma native continued to impress.

This time around, Underwood is spending her pregnancy preparing for the release of her next album, Cry Pretty; the project is due out on Sept. 14. Also this fall, she will return as the voice of the Sunday Night Football opening theme song and will be co-hosting the 2018 CMA Awards, with Brad Paisley, for the 11th consecutive year. In 2014, Underwood used her co-host Paisley to help reveal Isaiah's sex during their CMA Awards opening monologue.
