Listen to Kellie Pickler on iHeartRadio

Kellie Pickler says she had "so much fun" taping her appearance on ABC's "Nashville," and she "can't wait to see the finished episode." 

The country star admits this particular episode was special because of its location.  She explains that they went outside the show's namesake city to shoot at Fort Campbell, and she got the chance to entertain the troops and their families. 

The episode's plot line includes Connie Britton's character, Rayna Jaymes, putting together a charity event at the Kentucky Army base.  On the show Kellie performs her latest single, "Closer To Nowhere."  First Lady Michelle Obama also makes a special guest appearance. 

"Nashville" airs on ABC Wednesday night at 10:00 p.m. Eastern.
