Underwood's CMA Fest set previewed her Denim and Rhinestones Tour, coming soon this fall.

CMA Fest is an annual broadcasted music festival in Downtown Nashville that was filmed on June 9th-12th, when it was co-presented by ABC and Nissan.

The three-hour music event of the summer featured 30+ performances and surprise collaborations.

Some of Country music’s hottest stars, including Jason Aldean, were also in attendance.

Top country artists include Kelsea Ballerini, Kane Brown, Luke Bryan, Russell Dickerson, Lady A. Parker McCollum, Darius Rucker, Cole Swindell, and more.

The first-time hosts, Dierks Bentley and Elle King helped make the 49th Music Festival an event that will last in people's memories for years.

Elle's humor on stage, as well as her talent, is what makes her stand out.

The two of them had a lot of laughs together and there were many spontaneous moments.

Dierks will be the co-host and the event will be this weekend!

Underwood wore a red rhinestone encrusted Akira vest and dress to the event.
