Carrie Underwood [1] showed off her growing baby bump [2] while performing at the Ravinia Festival in Highland Park, IL, on Saturday. She sported a floral jumpsuit on stage and was absolutely glowing as she belted out her hits. It's the first time we've gotten a glimpse of Carrie's belly since she announced her pregnancy news [3] via Twitter last week. The country crooner shared a sweet photo of herself with her adorable dogs, saying, "In honor of 'Labor' Day...Ace & Penny would like to make an announcement. Their parents couldn't be happier!"

It's the first child for Carrie and her husband, Mike Fisher, and according to her, she's already feeling a few effects of being pregnant; in addition to reportedly forgetting which tunes she was supposed to sing next — Carrie asked her band, "Would anyone be kind enough to provide me a set list?" between songs — she also got a little emotional during a performance by fellow country stars Garth Brooks and Trisha Yearwood. Carrie shared a video of their set [4] on Instagram that evening and wrote, "I may have gotten misty-eyed a few times. Hormones? Maybe. Amazing concert? Definitely!" Coincidentally, new mom Kelly Clarkson and her baby girl [5], River Rose Blackstock, were also on hand for the show! Keep reading to see the adorable photos of Carrie's baby bump.
