Less than a week after announcing her pregnancy, Carrie Underwood stepped out to perform at Ravinia Festival with her baby bump in full view.

Underwood performed two nights at the United States' oldest outdoor music festival over the weekend, Sept. 6 and 7. And leave it to the 'All-American Girl' to make being pregnant so very fashionable. The star was  gorgeous and glowing onstage in a colorful floral pants romper. Not-so-hidden underneath the patterned outfit? The cutest baby bump.

On Labor Day 2014, the blonde beauty revealed on social media sites that she's expecting. She cleverly made a "labor day" pun while dressing her pups in big brother and big sister shirts for the occasion. This will be the first (non-furry) child for her and her hubby, Mike Fisher.

Underwood is due in Spring 2015.

Despite being in the early stages of her pregnancy and possibly dealing with morning sickness, the singer is a busy little bee. She played two nights at the Highland Park, Illinois Festival and also made her 2014 NFL season 'Sunday Night Football' debut on Sunday night (Sept. 7). Her rendition of 'Waiting All Day for Sunday Night' premiered before the kickoff game between the Denver Broncos and the Indianapolis Colts.

In addition, Underwood is hosting the 48th annual CMA Awards alongside 'River Bank' singer Brad Paisley. Come Nov. 5, Underwood's bump will have grown quite a bit when she takes the mic live in Nashville, and we can't wait to see! Did we mention she's also playing executive producer on a new TV series? Girl is busy!
