First, we have to flashback to March 5th when Little Big Town invited Kelsea Ballerini to become a member of the Grand Ole Opry. After Kelsea's performance, Little Big Town took to the stage to close out the show and invited her back on stage to sing "Girl Crush" with them. The lyrics changed just slightly at the end, watch the moment again below: 

Second flashback is this past Tuesday (April 16) when Kelsea officially became the newest and youngest member of the Opry, being inducted by Carrie Underwood. Not only did Carrie officially introduce and induct her, but they sang a duet together. Check out their cover of this Trisha Yearwood classic, "Walkaway Joe"! 

Congratulations again to Kelsea Ballerini, it is quite an honor and accomplishment to be a member of the Grand Ole Opry!
