The former American Idol winner-turned-country superstar looked gorgeous as she arrived for the American Country Countdown Awards on Monday night.
Carrie is expecting her first child with hockey player husband Mike Fisher, who was also in attendance at the event.
The couple have already confirmed it's a baby boy.
Carrie recently revealed how she and Mike chose to learn the baby's gender: rather than having a doctor tell them during an appointment, they asked the doctor to write the baby's sex on a piece of paper and seal it an envelope.
Then, over dinner at a cosy restaurant, the parents-to-be opened the letter together to find out.
"The doctor's office is kind of a sterile place," she told ABC News Radio. "We got to see all the pictures and everything, and it was really cool to see that, but whenever she'd get near, near those parts we would look away."
It was just the two of us in a nicer setting [than the doctor's office] but we both knew. So, that was just confirming our suspicions. We didn't really speak of it before then because we were both just like, 'Whatever, it's all good.' But we knew it was a boy."
Last night marked the inaugural American Country Countdown Awards, which honours the year's best in country music.
Carrie opened the show with a medley of her greatest hits including 'Blown Away', 'Cowboy Casanova' and 'Before He Cheats', alongside new track 'Something In The Water'.
