The country music star arrived on the 52nd Annual CMA Awards red carpet in a stunning long-sleeve embroidered floral gown by Uel Camilo, Anabela Chan ring andJN Jewels earrings on Wednesday evening in Nashville, Tennessee.
Underwood showed off her growing baby bump as she adorably cradled her belly for the photographers.
She was joined by husband, former hockey pro-Mike Fisher. The couple are parents to their 3-year-old son, Isaiah.
"It's definitely different than the first time," Underwood confessed. "When they say every pregnancy is different, it really is. Just different symptoms. I feel like this one is just a little harder on my body for some reason. But it's been really good."
The blonde beauty hosted the country music extravaganza alongside Brad Paisley. The expectant star began the show in the first of many outfit changes via a bright pink floor-length coat by Stello and leather pants.
Underwood donned a bubble wrap dress jokingly gifted by Paisley, poking fun at her frightening fall last year, which resulted in 40 to 50 stitches in her face. Shortly after she revealed the embellished Maison Alexandrine mini she wore underneath with silver Ruthie Davis shoes and Loree Radkin jewelry.
The former American Idol winner wowed in a blue gown with dramatic caped sleeves by Stello and Jared Lehr earrings during her performance.
Underwood looked like a golden goddess in a sparkly dress with side-swept tresses.
The performer was gorgeous in a navy blue velvet dress as she accepted the award for female vocalist of the year.
