Listen to Carrie Underwood on iHeartRadio

Carrie Underwood is celebrating five years as a member of the Grand Ole Opry.  The country star hit the milestone last month, and she'll be celebrating the occasion tonight.  She's closing out both shows, which are each dedicating the last half hour to her. 

Other stars will also be on hand to add to the festivities.  Josh Turner, Lauren Alaina, and Casey James are set to perform during both shows, along with Bill Anderson, Charley Pride, and Mel Tillis.  Jim Ed Brown and Jennie Seely are also part of the early show's lineup, while Jan Howard and Bobby Osborne and The Rocky Top X-Press will take the stage for the late show.
