Kelsea Ballerini

The pair will share the stage at downtown Nashville's Ascend Amphitheater on Oct. 11.

The new song is stripped-down and emotionally vulnerable.

"I think now that I’m married, it gives me such a perspective on the other relationships that failed me," says Ballerini.

She's worked with some very exciting new collaborators.

Darius Coleman wrote the brand-new song.

Reunited and it feels so good!

She had Carrie Underwood by her side!

Ballerini was all smiles and happy tears for her official entry into the hallowed institution.
