Carrie Underwood's comeback to country after giving birth to baby Isaiah Michael Fisher has been a very successful one, and it just keeps getting better. The proud mama sold out four shows at the Grand Ole Opry in just one weekend.

The Opry is an important staple at the heart of country music and, similar to Underwood, they're celebrating something too. The Opry is now a whopping 90 years old, and to commemorate nine decades they are celebrating for nine months. For four nights of their lengthy birthday party, Underwood took the circle and wowed the crowd with her voice and stage presence. Fans were thrilled about the special event, and every night sold out!

Underwood stunned during her performance in an ivory v-neck gown. The sparkles on the dress shone under the Opry lights. She wore her hair up and a little messy for a very glamorous look. The Opry said it best on their Instagram page, writing, "She just gets better every time we see her!" and using the hashtag #bestweekendever. We couldn't agree more.

While on stage, she sang some of her biggest hits to the delighted audience. Underwood sang "Little Toy Guns," her most recent No. 1 hit, as well as the beautiful "Something in the Water." She belted that one out, probably leaving more than one person in the audience with chills.

The blonde beauty has come a long way in her career, and she's really just getting started.
