Carrie Underwood stepped out for the first time since her pregnancy announcement on Sept. 1 to perform at the Ravinia Festival in Highland Park, Ill. The 31-year-old singer looked radiant as she performed for two nights on Sept. 6 and 7.

In this photo tweeted by a fan (courtesy of Taste of Country), Underwood is seen wearing a floral dress and sporting a very visible baby bump at the outdoor music festival.

The country superstar announced on Labor Day that she and NHL star Mike Fisher were expecting their first child. Underwood is due in spring of 2015.

Between now and then, however, she has a lot on her plate. Underwood is also the star of Sunday Night Football on NBC and made her debut during last night's broadcast of the Indinanapolis Colts vs. the Denver Broncos. She will also be co-hosting the CMA Awards with Brad Paisley on Nov. 5.
